Users can also experience impulsiveness and shifts in emotions that occur so rapidly some users report that they seem to experience several emotions at the same time. One problem with using LSD is the effects are unpredictable. Users never know if they are going to have a good "trip" or a bad one.
The long-term effects of using LSD can include persistent psychosis (disorganized thinking, mood disturbances) and flashbacks. Users can experience these long-term consequences sometimes after only one exposure to the drug.
