What can LSD feel like?

LSD can change how you think, how you feel and how you understand yourself, the people and the world around you. The intensity of these changes depends on the dose and how you are feeling. It is important to know that it can be difficult to judge how ‘strong’ LSD is just by looking at it.

The effects of LSD can come on from about 20 minutes to just over 1 hour after taking it. These effects can last 6–15 hours, but most people will not have a trip that lasts longer than 12 hours. Remember, a low dose for one person can be a high dose for another as people’s bodies process drugs differently.

 A female in her 20s talks about her first experience using LSD:

“At first the trip, the internal scenery of the mind, was pleasant, and we all started feeling giddy. I began to notice people looking at us, imagining their judgement of four students acting strangely. I was torn between succumbing to the trip and retaining the self-awareness that usually made me a functional member of society.”
