Is there an antedote for LSD?

There is no drug or compound that will magically cure LSD intoxication. However, there are many drugs which can be given to someone on LSD that can reduce the symptoms of LSD intoxication help calm the user. Benzodiazepine medications (Xanax, Klonopin, Valium, Ativan) are given to reduce anxiety but will not reduce hallucinations. Atypical antipsychotics (quetiapine, risperidone) are given to sedate the user and reduce hallucinations.
