Re: lsd detectable by sniffer dogs??
the crystals do not throw a scent... LSD cannot be traced by sniffer dogs, it does not throw an aromatic compound, and the very little that does proliferate into the atmosphere will be very little use to drug dogs.
in all fairness, the drug dogs don't sniff out the 'drugs', they sniff out the impurities that aren't alkaloidal; in the case of meth and cocaine, and mushrooms/weed are natural... dogs sniff out the terepines in marijuana, and definitly would not respond to 100% pure psilicybin or psilocin.
heroin does however have a distinct scent when pure (as far as swim's research shows).
another good note is that drug dogs need to be seeded, just like cadaver-dogs and bloodhound trackers, they need to sniff what they need to find... if the carrier doesn't have a 'ball' for that scent, they'll be out of luck, and since it'd be almost impossible to know what impurities would come in any given batch of LSD, and the absolutely miniscule amounts nessesary, I'd be confident in saying you could have 50milligrams of LSD crystals in the open air and dogs would not be interested.
