White drugs are a category of drugs that are considering to be the worst of all of the drugs. They're called White Drugs because they tend to be white in colour, but don't refer to every single drug that is white.

White drugs is used most commonly to refer to heroin, methamphetamine and other types of speed, cocaine and PCP. Other drugs that are white in colour such as ecstasy, ketamine and research chemicals are not included.

Some habitual drug users vow not to use white drugs due to the fear of addiction but do use other drugs such as marijuana, alcohol, ecstasy, LSD and other hallucinogens.
