just thought i would chime in on the tax stamp. my sister is an economist for the massachusettes department of revenue and they have the marijuana tax stamp, as well as stamps for other illegal drugs. many drug cases begin as tax evasion cases, or when busted, dealers are also charged for not paying the taxes on the drugs and income. well, the state cant prosecute for tax evasion unless they create an avenue by which citizens can pay their taxes, so, viola, the pot/cocaine/heroin tax stamp. Just like the tax stamp for booze and tobacco. of course, no one ever buys the stamp for obvoius reasons.
