The feeling you got your first good smoke, but this hits harder, like a train, 10-15 minutes in. High last about 1 hr-1 1/2 hr, but the insane cerebral high, lasts under a half hour. Makes you very confused when you come down, which causes a lot of paranoia. After-effects can leave you confused for days.
One of the best out there. Pure Indica, a slower strain. Great to watch movies or trippy videos, listen to Floyd or Jefferson Airplane. Also gave me a giant, long lasting erection.
