What do you mean "in their time"? They've been in business since the 1800s.
Bayer used to produce heorin, morphine and opium tonics back in the early 1900's, many of which were used for pain, illness, alcoholism, but they just ended up making things worse.
The history channel had a special about opium and I was shocked to see how many companies produced legal opium based meds, which were over the counter, in the early 1900's and late 1800's.
Marijuana was in something like 95% of medications back then, and it was actually the safest.
Bum, give me a reason for the banning for marijuana. Alcohol is worse and that's obvious, but is legal, while marijuana is not. Why? Alcohol can impair far worse, cause car accidents, death from over drinking, violence. Marijuana can not be overdosed on, nor does it make people violent. And contrary to reports by the DEA, marijuana does not cause cancer like tobacco, as it's not grown in radioactive soil. And I've never seen cases of accidents cause by marijuana comprable to alcohol related accidents.
