New Yorkers 21+ are now allowed to possess cannabis, legally. If you're going to enjoy, remember it's unsafe and not legal to drive while using or while high from cannabis.

Here are some more important facts to keep in mind:

  • Smoking or vaping cannabis is prohibited anywhere smoking tobacco is prohibited. It's not allowed in parks or restaurants or motor vehicles.
  • Cannabis cannot be used inside a vehicle, by drivers or by passengers. The law includes consuming or simply lighting a cannabis product and applies to parked cars too.
  • Cannabis use, before or while driving, can negatively affect a number of skills required for safe driving:
    • It can slow your reaction time and ability to make decisions
    • It can impair coordination and distort perception
    • It can lead to memory loss and difficulty in problem-solving
  • THC, which is the main active ingredient in cannabis, affects areas of the brain that control your body’s movements, balance, coordination, memory, and judgment.
  • Drivers' risk of serious injury or death from a car crash is greater when using cannabis in combination with alcohol, cocaine, or benzos than for using each drug by itself.
