weed isnt the gateway, youre the gateway.. if you smoke weed and dont wanna do any other drugs, then nothin and nobody is gonna make you.. if you give in and do other drugs tis your fault.. just because u smoked weed before u used herion doesnt mean youll do herion after you smoked.. if thats the case, then coffee, chocolate, aspirin, damn even apples and oranges are gateway drugs, because im sure every herion addict has tried all of them before he/she got on to herion
