Is it true that LSD stays in your spinal cord?

No, that is incorrect! There are people who think that LSD stays in your spinal cord or fat.

If you have taken a drug, your liver breaks down the drug and it is mainly excreted through the urine. The drug doesn’t stay in your spinal cord or fat. The only exception to this is cannabis. That also goes out of your body, but stays in your body a bit longer than most other drugs. This is because cannabis is very fat soluble.
