How could this assembly be formed effectively? There would be membership, including a fee. The fee would go almost exclusively to a team of lawyers and spokespeople (the rest going towards creation and distribution of membership cards). Membership would provide full legal protection under the team of lawyers and spokespeople, as well as granting access to participating drug-bars. The bars would be private institutions where drugs could be used and traded for use elsewhere.

Because the membership fee's go almost entirely to the legal team, membership cost would be inexpensive. If you have a million members paying only $20 a month, you have a highly powerful legal team. Of course, the businesses involved would also have to be members and would pay a higher fee than a single drug-user.

There are currently two main Constitutional protections being breached (4th and 8th amendments). The 4th amendment forbids the government from unreasonable intrusions of privacy. The 8th amendment forbids any excessive punishment (if something should go unpunished, any punishment is excessive - like imposing a fine for breathing). With the addition of an assembly, 1st amendment protections would also apply. The assembly being organized properly gives drug-users the best possible protection from government tyranny.
