Why do heroin addicts use lemons?

The brown heroin commonly seen in the UK doesn't dissolve very easily and is therefore difficult to inject intravenously. Users have to use acids, usually citric acid from lemons, to do so.

Marijuana & Ecstasy - how long after use will these drugs show in a blood test?

Blood tests are highly accurate but expensive, so most drug tests use urine or hair. THC, the active ingredient in cannabis, is detectable in the urine for up to two days for one-time users to 6 weeks for chronic users. MDMA or Ecstasy, on the other hand, can be detected or up to 72 hours.

How long will mushrooms (psilocybin) be detectable on a hair test?

Technically, between 3 to 5 months after use, but psilocybin is not usually tested for in standard (cannabis, cocaine, amphetamines, opiates, PCP) or advanced drugs tests (barbituriates, benzodiazepines like Valium).

Is it true that doing LSD can destroy your reproductive system?

This theory originated from a study in the late 1960s which showed that LSD caused "chromosonal breaks", or damage to DNA, and it was inferred that LSD could cause birth abnormalities. The study, however, failed to mention that nearly all drugs, legal or illegal, cause chromosonal breaks - including aspirin, caffeine, antibiotics, and artificial sweeteners, the majority to a greater degree than LSD.

However, like all drugs, LSD should be avoided during pregnancy. Ergot, the fungus from which LSD is synthesized, can induce uterine contractions.
