Well, if you have to do a school project and you have the choice to do it on drinking, smoking, and drugs, and you're interested in that stuff, why not? Learn while doing, exactly. It may surprise some, but a lot of people who do drugs actually do like to learn about what they do to the body, both to enhance the experience, and to be safe. Learning about it becomes a sort of interest/hobby as much as actually doing the stuff does.
If only everyone who wanted to experiment with drinking and drugs had the wherewithal (or ability/opportunity in some cases) to research it. It makes everything safer, to be informed.
