Should I smoke Medical Weed before lifting weights ?

I am 5`11/160lbs. Yeah pretty skinny kid if you might add lol. I do somewhat lift weights but im very inconsistent,although, once I do get started and stay with it like how I should ... Should I start getting high before a workout because I have done it once and that is what gave me the idea to try it. You go through with the pain having a better workout overall because its going to be fun. Also, might I add I play football for a Jr. College and it would be a very good idea to get bigger. I play WR and no they dont drug check you.
