Lysergic acid diethylamide (LSD) is an illegal hallucinogenic drug that changes how people see, hear, and feel things. In the United States, it’s against the law to use, own, or sell LSD, but some people still use it recreationally to get high. The drug usually comes in different forms like small tablets, capsules, pieces of paper called blotter paper, or sometimes as a liquid.

People who use or sell LSD often call it by different slang terms or street names instead of using its real name. They do this to hide what they’re talking about from police officers, parents, teachers, or other authorities who might be listening. These code words also help drug users and dealers communicate with each other without being obvious about illegal activity. Knowing these street names can help parents, teachers, and others recognize when someone might be talking about or using this dangerous drug.

People who use or sell LSD may use certain street names to refer to specific forms of LSD. The most popular names for drugs shift over time and may differ based on where you live.

Street Names For LSD Combined With Other Drugs

People who use LSD sometimes mix it with other dangerous drugs to create stronger or different effects. This practice is extremely risky because combining drugs can cause unpredictable and life-threatening reactions that are much worse than using just one substance alone.

When LSD is mixed with other drugs, it gets special street names that describe the combination. For example, “black acid” refers to LSD mixed with PCP, a powerful drug that can cause violent behavior and serious mental problems. Another dangerous combination called “backbreaker” mixes LSD with strychnine, a poison that can cause severe muscle spasms and death. These drug combinations are particularly dangerous because users often don’t know exactly what they’re taking or how their body will react.

How To Recognize LSD Use In Someone You Know

Because LSD produces intense sensory effects, recognizing when someone is under its influence is often straightforward. A person who has recently taken LSD may appear confused or detached from reality, react emotionally to things others cannot see or hear, or show physical signs like dilated pupils, sweating, and loss of appetite. A bad trip can cause extreme panic or paranoia that may resemble a psychiatric emergency.

Longer-term use can be harder to identify since LSD does not cause physical dependence. Behavioral warning signs include withdrawal from friends and family, declining performance at school or work, and secretive behavior around drug use. Some heavy users develop hallucinogen persisting perception disorder (HPPD), where visual disturbances continue long after the drug has worn off.

Treatment For LSD Abuse

People battling psychedelic drug abuse need professional help to safely stop using and learn healthy coping skills. Treatment for drugs like LSD requires a combination of different approaches because these substances affect both the mind and body in complex ways. Getting the right drug abuse treatment can help people recover and prevent serious long-term health problems.

Treatment options for psychedelic drug abuse include:

  • detoxification programs to safely stop using drugs
  • inpatient treatment centers for 24-hour medical care
  • outpatient counseling and therapy sessions
  • group therapy with other people in recovery
  • individual counseling to address personal issues
  • cognitive behavioral therapy to change harmful thinking patterns
  • family therapy to repair relationships and build support
  • medication to treat depression, anxiety, or other mental health problems
  • support groups such as Narcotics Anonymous
  • aftercare programs to prevent relapse

Getting help early can prevent more serious health problems and help people build a healthier, drug-free life. Anyone facing psychedelic drug use should talk to a doctor, counselor, or the Substance Abuse and Mental Health Services Administration (SAMHSA) for more information.
