[shrug] So it goes.
The argument goes like this: most users of “hard drugs” probably used marijuana before using cocaine, meth, heroin, and so on. Therefore – so the argument goes – pot is a gateway into the “hard drugs”.
Well, most people who drink alcohol probably started out drinking coca cola or pepsi. Does that mean that colas are a gateway into vodka?
Most people who smoke probably started out chewing gum or sucking on jawbreakers. Does that mean candy is a gateway into cigarettes?
Here’s the point: correlation is not causation. If you don’t know what that means, look it up or ask somebody. If you’re not willing to make even that minimal effort, then you sure as hell have neither the intellectual equipment nor the integrity it takes to stand behind anything that states or even implies that marijuana is a “gateway drug”.
