How much marijuana can you legally drive with in your car in Michigan?
Dave Bartkowiak Jr., Digital Managing Editor
DETROIT – We get a lot of questions about Michigan’s marijuana laws through our 4YI form, where you can ask us anything about Michigan and/or Metro Detroit and we will do our best to return with the answer(s).
For instance, we’ve done our best to answer questions about legally growing marijuana at home — see that here. Now that marijuana is being sold legally in the state, we’re seeing a lot of questions about how much you can buy at once and how much you are allowed to drive around with in your car.
“If I’m on the way home from buying (marijuana), how much can I legally have in my trunk? I often buy from several favorite shops in Ann Arbor and am curious!” — Anonymous
The answer is no more than 2.5 ounces of marijuana. If you are at least 21 years old in Michigan, you are allowed to have up to 2.5 ounces of marijuana (not more than 15 grams of marijuana may be in the form of a marijuana concentrate, such as edibles) in your vehicle. It doesn’t matter if it’s in your trunk or not, although you probably want to keep it somewhere concealed. The trunk is not a bad idea.
As for what police might be looking for if they pull you over, this is straight from Michigan State Police:
- Drivers cannot operate, navigate, or be in physical control of any motor vehicle, aircraft, snowmobile, off-road recreational vehicle, or motorboat while under the influence of marijuana.
- Drivers cannot consume marijuana while operating, navigating, or being in physical control of any motor vehicle, aircraft, snowmobile, off-road recreational vehicle, or motorboat. Drivers and/or their passengers are prohibited from smoking marijuana within the passenger area of a vehicle upon a public way.
- Drivers and passengers cannot transport marijuana into Canada (against federal law).
- Police officers will be looking for impairment based on driving, personal observations of the driver, and how a driver performs on standardized and/or nonstandardized field sobriety tests. Based on these three stages of an investigation, a police officer may request a chemical test. If a driver refuses to submit to a chemical test, his/her license will be suspended pursuant to Michigan’s implied consent law. Under this law, all drivers are considered to have given consent to the test when they apply for and renew their driver’s license.
- The penalties for operating under the influence of marijuana are the same as operating under the influence of alcohol. These penalties can include up to 93 days in jail, up to a $500 fine, license suspension, six points on a person’s driving record, and more. There are heightened penalties if a driver has minors in the vehicle.
Businesses can’t sell you more than 2.5 ounces at one time
If you’re buying marijuana from a licensed shop, you should know Michigan law actually prohibits that shop from selling you more than 2.5 ounces of marijuana in a single transaction.
“A marijuana retailer is prohibited from making a sale or transferring marijuana to an adult 21 years of age or older in a single transaction that exceeds 2.5 ounces, except that not more than 15 grams of marijuana may be in the form of marijuana concentrate,” reads the law.

Marijuana Laws in Colorado
With the passing of Amendment 64, adults 21 or older in Colorado can legally possess one ounce (28 grams) of marijuana or THC.
If you are an adult 21 years of age or older, you can now legally possess 1 ounce of marijuana in Colorado. The way the amendment is worded actually allows for possession of 1 ounce of THC. This is great news because in addition to flower (bud), you can also enjoy many types of concentrates, edibles, topicals, etc. during your visit. Cannabis seeds are also available for sale in Colorado.
As long as you are 21 years or older, you have a constitutional right to possess and consume marijuana in Colorado. You will need a government-issued identification to prove you are 21 years or older, so a drivers license or passport would be sufficient enough. Note that you don’t need to be a Colorado resident to possess recreational cannabis and there isn’t any type of registration system. Only residents who apply for medical marijuana cards need to register with the state. Medical patients may possess up to 2 ounces.
Previously, tourists in Colorado were restricted to purchasing 7 grams or less, while Colorado residents could purchase up to 28 grams. This law changed in June 2016, and now both tourists and residents can purchase 28 grams in a single transaction. Medical patients may purchase up to 2 ounces of medical marijuana or its equivalent as a standard, though higher amounts may be granted by the recommending physician.
The law has some grey areas regarding what constitutes a ‘single transaction,’ so most recreational stores err on the side of caution and will only serve you once a day. In the past, circumventing purchasing limits has been punishable by fines or even jail.
As of October 1st, 2016 the laws have changed.
The Marijuana Enforcement Division (MED) in Colorado performed studies to determine what the THC equivalent of concentrates and edibles are in relation to marijuana in flower form. They argue that since products such as concentrates have a much higher level of THC, then you shouldn’t be able to purchase the same amount of concentrates as you can flower. As a result, the MED has issued ‘Marijuana Equivalency’ guidelines.
As of October 1 st , 2016 the following rules took effect in regards to recreational sales (medical sales remain unchanged):
- 1oz Flower = 8g of Concentrate (Shatter, Wax, etc)
- 1oz Flower = 800mg of Edibles
You can still mix and match, but it gets confusing. For example, you can purchase 2 grams of concentrate, but then you will be limited to buying an additional 3/4 oz of flower (as 2 grams of concentrate is now equivalent to 1/4oz of flower). These laws will be a big challenge for budtenders as they attempt to sell combinations of products while ensuring that the buyer is within the legal limits.
One important thing to note is these restrictions only apply to retail sales, not possession. You can legally possess up to 28 grams of concentrates or THC as defined in the Colorado Constitution. Where to Buy

Currently, the state allows marijuana stores to operate from 8am until Midnight. Having said this, cities are allowed to establish their own rules within the allocated timeframe. For example, Denver stores must close by 10pm. If you’re looking to purchase marijuana in Denver after 10pm, head to Edgewater and Glendale (two cities bordering Denver), which both allow stores to stay open until 12am. Another great option is Aurora, which allows stores to stay open until 10pm as well.
So you made it to Colorado and bought yourself a big bag of green. Great job! Now the question is: “Where can I smoke my weed?” This is a highly debated topic at the moment, so here’s some helpful insight into what’s legal and what’s practical.
First and foremost, you will find the following statement to be true during your visit:
Discretion is appreciated, and usually required.
Amendment 64 does NOT permit the consumption of marijuana “openly and publicly.” So before you start blazing those blunts while walking down the street, remember that you can still get a ticket for doing so, similar to open container laws for drinking in public.
In general, there aren’t any coffee shops or marijuana bars where you can purchase cannabis products like you might find in Amsterdam. However, thanks to Initiative 300, bring-your-own-cannabis lounges are beginning to open their doors to consumers.
In addition to the new social consumption lounges, several ‘private’ cannabis clubs are open to adults as well. These clubs are a great place for tourists and locals alike to come together and consume marijuana products safely and legally. Some even allow indoor smoking since they are ‘private,’ while others just allow inside vaping and outside smoking.
Remember, public consumption is illegal and can result in tickets and fines. Denver Police have also increased citations for public consumption over the years. In the first three quarters of 2014, Denver Police issued 668 public consumption citations. This amounts to a 470% increase from the same period in 2013, when 117 citations were issued. On 4/20 in 2018, police issued 72 citations, almost twice as many as the previous year.
Even though concert venues and bars are considered ‘private,’ prohibitionists argue that they are ‘publicly accessible private venues’, and therefore consumption of marijuana is prohibited. From our experience, it depends upon the place and the crowd. Most down to earth venues will usually turn a blind eye to things unless they are getting complaints or police visits.
To be discreet, edibles or a portable vaporizer can be your best friend. These have become very popular in Colorado, as they don’t really leave any odor and can be consumed almost anywhere. Social Lounges
Driving Under the Influence
A new DUI law is in effect in Colorado which sets a legal limit for the amount of active THC in your system while driving. The legal limit is 5 nanograms per milliliter of blood. This law was fiercely debated with the main issue being that people metabolize THC at different rates and as a result, the amount of impairment varies drastically from person to person. Unlike alcohol, where if you are over 0.08 you are impaired, it’s hard to determine if a person is impaired or not based upon THC levels alone.
The bottom line is be smart and don’t drive under the influence. If your car doesn’t smell like you ran over a pack of skunks and your eyes aren’t bloodshot, it is unlikely that you will be singled out. If the police do suspect you are driving stoned, they can require you take a blood test. Refusal to do so can result in similar penalties as refusing a breathalyzer test, such as loss of license.
The possibility of being involved in a serious car accident, even through no fault of your own, always exists, so it’s best to sleep off the high. The law does allow for a defendant charged with driving under the influence of marijuana to introduce evidence that pot did not impair their ability to drive. This is a last ditch strategy, the best advice is to simply drive sober.
In 2014, 354 people received marijuana only DUIs in Colorado. If you find yourself in need of legal representation for a marijuana DUI, we recommend Jeff Gard from Gard & Bond.
Colorado legalized recreational marijuana for in 2012 but legal cannabis sales did not start until 2014. We offer practical information about marijuana laws, regulations, and statutes for residents and those planning a trip or vacation to Colorado.
