LSD is a popular psychedelic drug. It is referred to on the streets by a number of names including acid, mellow yellow, blotter acid and dots.  In the United States, it is a Schedule 1 drug. Drugs classified as such are those that have a high potential for addiction and abuse and have no noted medical uses in the United States. Schedule 1 drugs will often result in the most severe punishments. These typically carry the harshest sentences if individuals get caught with them especially with the purpose of distribution.

Though LSD is a psychedelic drug and most people associate hallucinations and changes in the senses with its use, its effects are in fact, unpredictable. While some individuals may in fact hallucinate and are significantly affected by the drug, others will not be. When LSD does work, an individual’s personality and mood will typically change.  

Users will begin to experience the effects of the drug about 30 minutes to an hour after they use it. It will generally clear the system in about 12 hours.  When the drug does “work,” individuals may experience a dramatic change in their senses. They may feel like they can 'hear colors' and 'see sounds', essentially a reversal of the normal sensory experience. A person may also see things and hallucinate.  

Physically, individuals may find it difficult to sleep after taking acid.  They may have the shakes, dry mouth and begin to sweat. Acid may also increase the blood pressure and heart rate.  Individuals that take LSD chronically and long term will experience unique effects.  This might include flashbacks of past LSD use.  They are also at risk of becoming depressed, experience psychosis and even schizophrenia.

Even though LSD isn't considered a physically addictive drug, it can be psychologically addicting. Some people may feel compelled to use the drug even when they recognize the associated dangers. Most people won’t require rehab in order to so stop using LSD, though some might. Those that do may find that outpatient rehabilitation is effective. It will give users the opportunity to speak with a trained drug counselor about their addiction and develop strategies to avoid the use and abuse of LSD.
