Boing Boing: Sheriff: tweakers compulsive seek out ancient indian arrowheads
An ex of mine was a Meth addict.
Her particular thing was beading; she made dresses for drag queens for a living, and used to sit up for nights on end sewing bugle beads on to her creations.
One of her dresses is still worn by a Bette Middler in a Vegas drag show. At the time, my ex was so skinny that the dress actually weighed more than she did when finished.
