Many people ask me if you can get charged with a DWI after smoking marijuana, and the answer is yes and no. It depends on the circumstances. There’s no per se limit. In other words, there’s no limit of THC that, as a matter of law, you can have in your body like alcohol. For example, alcohol is a .08 limit. There’s no such limit for THC or marijuana. However, if you smoke so much marijuana that you’re impaired – that is to say you no longer possess your usual skill, intellect, or physical control of yourself because of the amount of marijuana you consumed, then you could be found guilty of driving under the influence of marijuana.
