Lysergic acid diethylamide, also known as acid, is a psychedelic drug known for its psychological effects. LSD is banned as Class A drug around the world.

But there are some alternative for the drug which is available freely in the market today they are also sold online.

1P-LSD

1-Propionyl-lysergic acid diethylamide (commonly known as 1P-LSD or 1P-LAD) is a novel semi-synthetic psychedelic substance of the lysergamide chemical class that produces "classical psychedelic" effects reported to be near-identical with those of LSD when administered. Like ALD-52, it is principally theorized to act as a prodrug for LSD, not exerting any activity until it has been converted into LSD after entering the body, although there is ongoing speculation that it might possess some intrinsic activity in its own right
