Does marijuana have any effect on a driver judgment?

I sometimes miss my exit.

And sometimes I forget where I'm going.

I posted the first answer too but I pressed the"Post This Answer" box before I'd finished what I had to say.

I think this indicates, that the definitive answer to your question is "yes".My driving is definitely affected in a very positive way.Because I sometimes forget my destination,the route to my destination or a catastrophic combination of both,(imagine not knowing how to get to where you don't know where you are going),I spend a great deal of time driving.I think that because of all the practice I get,I must be really good at it.

I hope this gives you some closure and that you are able to move on now.
