What are the longest lasting street drugs?

Here are some of the "worst", based on their effects and/or how they affect the body:

-Methamphetamine: the high can last several hours, but many users report still feeling the drug "working" on their body for hours afterwards. Crystal meth is very damaging to the body over time.

-Heroin: depending on the purity and frequency of use, a heroin high can last from around 2 to 8 or so hours.

-The effects of cocaine and crack cocaine don't last very long- for regular cocaine, around an hour or so, and for crack, only several minutes to an hour. That contributes to frequent usage and how addictive they are.

-PCP (Phencyclidine): Definitely one of the worst illicit substances and a very powerful dissociative hallucinogen, but it's pretty unpopular in general due to it's effects, which can last for around 6 hours and include: numbness, extreme moods (like euphoria or rage), schizophrenic behavior, visual/auditory distortions, violent aggression, very reduced sensitivity to pain, and severe delusions- like believing you are invincible and so you step out in front of a bus, or believing you can fly and so you throw yourself out of a 30th story window. It can make it completely unable for you to perceive reality, and make you do things you wouldn't ever dream of doing.... Like slaughtering your family and/or yourself... Etc.

-An LSD trip can last for up to 12 hours or more. LSD sometimes has a nasty habit of "uncovering" or worsening already existing mental problems, and very heavy use can have some aftereffects. Not to mention a bad trip can make a person act very unpredictably, and have flashbacks that can occur years after the trip.

Peyote lasts the longer hands-down.

Based in the most common ones,( Pills ( Rivotril, Vicodin, Diazepan), Marihuana (Cannabisativa), Cocaine, Crystal).

Effect wise, crystal meth is the worst, cocaine is great after-party, I'd rather have a cigarrete than Marihuana.

Weed lasts in your system longer than anything
