Well, that covers our little visit to Substance Abuse City.
To sum up, our brilliant advice to all people reading and/or sharing this website info basically amounts to this:
Never take illegal drugs (and watch out for many legal prescription ones, too), don't smoke cigarettes (either the regular or "funny" kind), don't even hang out in smoke-filled rooms, and don't drink alcohol, sodas or coffee; drink healthy stuff like orange juice, tomato juice and purified water instead.
(While we're on the subject, for the more iron-willed among you, it wouldn't be a bad idea to go all the way and become a vegetarian, either.)
Addictive chemicals were a Pandora's Box of evils that never should have been opened. But now that it has been, there's no going back. So all you can do is try as much as possible to avoid it like the plague, because it literally is a type of plague upon every society in our modern world.
Of course there's little difficulty in giving such advice. The trick is in taking it... before it's too late.
Good luck, folks - you'll need it!
