Some have suggested that administration of niacin
(nicotinic acid, vitamin B3
) could be useful to end the LSD user's experience of a "bad trip".
The nicotinic acid in niacin
as opposed to nicotinamide
, will produce a full body heat rash, which is caused by widening of peripheral blood vessels. The effect is somewhat akin to a poison ivy
rash. Although it is not clear to what extent the effects of LSD are reduced by this intervention, the physical effect of an itchy skin rash may itself tend to distract the user from feelings of anxiety. Indeed, nicotinic acid was experienced as a stressor by all tested persons. The rash itself is temporary and disappears within a few hours. It is questionable if this method could be effective for people having serious adverse psychological reactions.
I think it would just make things worse.
