Those have a weird mix of ingredients,
It seems they've jus chucked in any legal but effective "substances"/herbs/seeds they could find.

Hawaiin baby woodrose seeds which contain LSA, primarily a hallucinogenic,
Calamus is quite stimulant/euphic and In higher mounts hallucinogenic,
AndI don't have any experience yet with piperazines (BZP)

If it was just one of those ingredients individually it would have been fine, but combinin them all together...

Combining any substances increases risk of things going wrong.

Cheers for the warnin on those
