TAP No. 55 - Test Your Stash: Drug-ID Column Debuts

TAP No. 55 - Test Your Stash: Drug-ID Column Debuts

Introduces ‘Test Your Stash’ by pseudonymous columnist Oz Y. Mandias, the first in a planned series on drug identification aimed at readers wary of adulterated street drugs. Explains the Marquis reagent color test (a formaldehyde/sulfuric-acid solution) and provides a reference chart of the color changes it produces with various substances, framing it as a basic harm-reduction tool rather than a purity guarantee. A short wire-service item notes phone company billing troubles making the rounds.
