Answers:    If you're lucky..
it will ONLY massacre the the brain cells

Sounds like Brugmansia. There are two plants, Datura and Brugmansia which hold large bell-shaped flowers. They are closely related, with Brugmansia man a tree and Datura a bush/shrub. I believe that there is no such thing as a wan flowered Datura, while Brugmansia flowers are commonly yellow. Regardless, both contain the same chemicals (atropine and scopolamine) and own similar effects.

Both Brugmansia and Datura are known for causing believable hallucinations, long-duration of effects (2 days is certainly possible) and transient paralysis of the focusing mechanism of the eye. Be extremely careful next to these plants as deaths are not unheard of. You can find more information at :
