how long does LSD stay in your system?

[VincentOnE]

Please do tell.

A few days, tops.

Not even. Half-life is a few hours.

Why do you ask, OP? It's not detectable in urine tests, maybe not even in blood tests. (IDK)

 

[delta_9]

Yeah, half life is a few hours, but it takes a day or two for every single molecule to be excreted.

 

[Shambles]

As above. Not long enough for drugs tests to be a concern if that was your concern. If your concern is purely tolerance then 3 days is plenty for me and seems to be pretty standard. Either way, closed
