What make you thinks teen use weeds?
College "kids", not teens. But yeah, about 80-90% of the college kids I've known smoke weed. Probably more of them smoke weed than drink beer.... from my personal observations.
Based on the thread subject spelling, I bet I know what inspired this post... 
Don't assume... The typo I can blame on the virtual keyboard of my Android phone... and accidentally pressing Enter instead of Backspace... It posted mid-typo.
Actually, I don't smoke.... (anything).
See the heroin store thread for a discussion along similar lines.
My own opinion is that the US government loves to point to a technology, and make arguments in court along the lines of "the majority of uses are illegal / infringing / evil / etc., therefore, any use of that technology strong imply illegality" I'm not making a political statement about drugs or gambling; that's just the practical reality one finds with today's law enforcement.
The best way to make bitcoins a success is to convince legitimate, tax-paying, paperwork-filing merchants to accept bitcoins, and customers to pay them in bitcoins. Similar to how bitcoin's network remains intact as long as >50% of the network is not evil, we need >50% of well known merchants to be upstanding citizens in their respective jurisdictions.
One day, inevitably, law enforcement will have a bitcoin-related case, and having evidence of bitcoin's beneficial nature will be powerful and useful. Concrete example: presenting bitcoin as a way for donors to charities to remain anonymous is a powerful, positive argument for bitcoin.
If the bitcoin "brand" is generally considered to be a den of thieves, scam artists, tax evaders, and criminals, it gain increased law enforcement attention, and will be marginalized away from the general public. I want bitcoin to be as broadly successful as possible.
Yeah. You make lots more sense than my question does.
I suppose that there will be plenty of natural attraction anyway... Attraction that certainly won't need our help.... Like how the porn industry was naturally attracted to the internet, when it was invented... No one needed to ask them to sign up.
I don't know how to visit a Tor site (if that's that this link is).
