The brain becomes a kind of sanctuary where the drugs can't follow,

The drugs clearly aren't stopping the destruction of brain tissue,

I wouldn't recommend sex, drugs or insanity for everyone, but they've always worked for me.

We were somewhere around Barstow, on the edge of the desert, when the drugs began to take hold.

We had two bags of grass, seventy-five pellets of mescaline, five sheets of high powered blotter acid, a salt shaker half full of cocaine, and a whole galaxy of multi-colored uppers, downers, screamers, laughers... and also a quart of tequila, a quart of rum, a case of Budweiser, a pint of raw ether and two dozen amyls.
Not that we needed all that for the trip, but once you get locked into a serious drug collection, the tendency is to push it as far as you can.

KNOW YOUR DOPE FIEND. YOUR LIFE MAY DEPEND ON IT! You will not be able to see his eyes because of the Tea-Shades, but his knuckles will be white from inner tension and his pants will be crusted with semen from constantly jacking off when he can't find a rape victim. He will stagger and babble when questioned. He will not respect your badge. The Dope Fiend fears nothing. He will attack, for no reason, with every weapon at his command-including yours. BEWARE. Any officer apprehending a suspected marijuana addict should use all necessary force immediately. One stitch in time (on him) will usually save nine on you. Good luck.
