I firmly believe, because I am an optimist who knows that humankind is at its heart good and true and reaching for the stars aka evolving that in the future crack will give us all the (apparent, I speak not from xperience here) HIT that people love with ZERO bad stuff. No addiction, no teeth rot, no fucked up anything. You smoke it on your down time, that time that the Feds let you do what you like with when you're not working for no money and you're FINE. Because in the future drugs have been perfected and you only get the good things out of them.
For real, this seems way more realistic to me. People act like because life may improve in the future, no one would do drugs anymore. I don't buy it. Humans have a long history of experimenting with drugs. Non-human animals do as well. Hell, some monkeys like to get drunk. I also don't think all drugs are used for escapism. People often use them for enhancement or all sorts of other things. Shit, I know so many fellow science majors who are prescribed Desoxyn (methamphetamine) because of the long hours they have to spend in the lab. Some anesthesiologists have taken to abusing propofol because without it, they can't get enough sleep. It makes sense that they'd take something that can give you deep sleep but in a short period of time. I'd rather have an anesthesiologist doing that than not sleeping at all and then trying to put me under. And the idea of using something like LSD to escape your problems... LOL. I dunno, I use Star Trek more for escapism than I've ever used drugs for that purpose!
