Weed can be kinda fucked up the first few times, lots of people have sorta a bad trip. You should be more worried about the coke, white powders will take you places you don't want to go. I know that from personal experience, I'll bet I put a million dollars in my arm. I know, you'll never do that, I said that, too. Stick with the weed, after the first few times you won't weird out on it, coke is just the opposite, the more you do the more you tweak.
