LSD Timeline

The half-life of LSD is around 5.1 hours. How long do the effects of LSD last? Generally, the effects can last up to 12 hours.

Once orally ingested, the substance is quickly absorbed through the gastrointestinal tract and mucous membranes. The drug reaches the bloodstream and organs quickly, about 10 to 15 minutes after being ingested. The drug is primarily processed by the liver, where it is metabolized into a number of other inactive metabolites.

How long do the effects of LSD last and stay in your system? Within 24 hours, almost all the drug has been metabolized and excreted. Approximately 13% of the drug is eliminated as a metabolite 2-oxo-3-hydroxy-LSD (O-H-LSD). Research suggests that this byproduct is present in urine samples at concentration levels 16 to 43 times higher than LSD. Researchers have attempted to develop different methods for detecting LSD, but the fact that the drug is unstable, broken down so quickly, and usually taken in relatively small amounts presents challenges.

LSD Addiction Treatment

Taking any illicit substance is dangerous. Given the illegality of LSD and other Hallucinogens, there is a high potential for dealers to lace them with other drugs like fentanyl drugs, ketamine, or meth. These adulterants are not only highly addictive but may cause a fatal drug overdose.

How long do the effects of LSD last and how it can harm you? Tolerance and dependency develop during the course of repeat cycles of abuse as a number of physiological adaptations to hallucinogen use and residual changes in the brain and central nervous system functions take place. Some of the effects are dramatic leading to severe depression and other emotional, cognitive, psychomotor, and behavioral or personality disorders that are difficult to reverse.


A large majority of hallucinogen detox treatments are when the abuser suffers a “bad trip”, overdose, injury, or other medical complication from their hallucinogen abuse. Detox treatment for hallucinogens abuse and dependency primarily involves close observations and interventions for the dangerous side effects that hallucinogens can cause as well as the withdrawal symptoms that evolve as the drugs are eliminated from the system.

Stabilization is the first stage of effective treatment that may require medications such as anti-depressants, anti-psychotics, or anti-anxiety drugs to make sure the safety of the person and those around them can be ensured.

Counseling Services

Individual, group, and family counseling services are offered in the majority of mental health and substance abuse treatment programs to “get to the root of the problems”, improve communications and relationships, and motivate the abuser toward positive changes. . The structured guidance of a counselor helps the patient stay on track and in the right perspectives as they strive to achieve their potentials and goals of recovery.

Cognitive Behavioral Therapy

Cognitive-behavioral therapy (CBT) is a widely used treatment for hallucinogens abuse and addiction to help individuals identify negative thought patterns, emotions, and problematic behaviors and learn how to make healthy lifestyle changes that decrease the urges to use hallucinogens and other substances; paying particular attention to symptoms of psychosis, depression, and other co-existing mental health-related problems or dual diagnosis that are exacerbated by stress.
