Oh come off it. You mean illegal reasons. You know you do. If you believe people should be free to buy any kind of drug they wish then say so, I don't think HN would view it as too radical a view. But your post sounds like typical corporate bullshit.
So demand has increased 1000% since the low of $3 less than a year ago? I don't buy that reasoning. I think it is 90% speculation and 10% increased demand. Demand is increasing, but nowhere near the amount to explain the large price shifts.

So far, momentum is on the upside, but don't think that it will just neatly and asymptotically reach its "true value". Expect a lot of volatility. The fact there isn't a lot of volatility here means that consensus is that prices will continue to rise.
