Probably. At least the medical and recreational usage of Cannabis. That is already legalized in some countries/states. Cannabis is known to have good medical effects, but it also have undesired side effects. Even in medical use!
"On the other hand, a recent study of Journal of Transport & Health indicated that the numbers of fatal crashes involving marijuana after the recreational marijuana legalization or decriminalization have significantly increased in Colorado, Washington, and Massachusetts." - Effects of cannabis - Effects on driving - Wikipedia.
Just do not drive, if you consumed (or consuming) Cannabis.
