Afgani Kush
It varies from 7-15% and hash has round 40-50% THC
8-15% Depending on growing conditions. The THC content is slightly lower than other "white" varieties because of the ruderellis genes. These genes also decrease the yield however enable the plant to auto-flower.
It would take a large dose of pure THC, but for Marijuana, the articles I have read say that one would have to smoke about 1500lbs of weed in 15 minutes.
One scientist said that a lethal dose of THC would be reached by smoking of 15 pounds of marijuana in 15 minutes, although no one has accomplished that to test the speculation. There are no known deaths directly resulting from marijuana use alone.
150%
Contrary to popular belief, there is absolutely no THC in the black tar that builds up on your pipe/bong/etc.The reason you get high is due to oxygen deprivation.Except for the resin you scrape out of the bowl, it is slightly burnt weed, with the resin on it.
No. According to the related link below, only around 15 to 20 percent of teens smoke marijuana.
15 percent = 15/100 which simplifies to 3/20
15
15% = 15/100 or 3/20
Zero. There is not ONE case of a person dying from marijuana alone. The LD50(dose at which 50 percent of people die) is estimated(since nobody has ever actually died from marijuana is 1500 pounds (680 kilograms) of Cannabis to be smoked within 15 minutes. Even the most burnt out of potheads couldn't handle that. Not to mention that you'd die from smoke inhalation before you died from the THC in the marijuana. Now, if you throw other drugs into the part along with the Marijuana, then yeah....fatality is a possibility. But to answer your question, Nobody has died from Marijuana
Percent refers to a fraction with 100 as denominator.So 15% = 15/100 = 3/20.
