I think there was no fixed channel when this whole thing started, but I believe there are some people who emerged and started selling drugs at the time.  Right now there may be different dealers and channels but for a start I think only a few people were introduced to the drug and such a person would introduce the drug to a friend and soforth.
	I trust now that the opportunity to sell these drugs opened up at the time.  That is how the drugs were introduced.
