LSD influences one’s senses and stops a person from seeing danger or making sensible decisions. A person can self-harm himself or even die under the effect of LSD. Even after knowing all LSD information, people still knowingly take it. Experiencing acute depression, anxiety, and sudden flashbacks is pretty common. These hallucinations may continue even after many days of taking the drug. People with personality issues experience sudden flashbacks. But having flashbacks is just one part of the side effects. One may face long-lasting depression attacks after using it. Even healthy people face extreme hallucinations. It also produces tolerance. After taking once, every time one needs to take a higher amount of doses to reach the same intoxication. This can be the most dangerous thing as no one can predict the extent of the effects.
