Dependence, addiction and overdose risk

Dependence and addiction

LSD does not appear to be physically addictive, though users can become psychologically dependent. Regular users may feel compelled to use it to function effectively or feel good in certain situations – such as at parties or on occasions when they would normally use the drug.

Tolerance to the hallucinogenic effects of LSD can build rapidly if used repeatedly over several days. However tolerance quickly subsides once regular use has stopped.

There is little evidence that people experience physical withdrawal symptoms if they suddenly stop taking LSD.

Overdose

High doses of LSD will increase the negative effects of the drug. Death due to overdose of LSD is extremely rare. When deaths have occurred it has usually been due to suicide, dangerous behaviour and accidents related to its hallucinogenic effects.
