a)I think its fucking horrible, not enjoyable
b) Too many people compare salvia to weed, I know you said its not at all similar but frankly they shouldnt be in the same sentence together unless its how they are completely different, using the words "real alternative to bud" was a big NONO.
There is NO alternative, except for hash ( An I'm not talkin soap bar either.) but thats still cannabis at the end of the day.

There is NO other drug that gives effects like pot.

Kratom is ok, You HAVE to make a tea though, you'd virtually need to smoke your own bodyweight of powdered leaf for decent effects.

Get a job and buy some weed.
