Marijuana is the oldest known psychoactive drug consumed for thousands of years, but there is still so much to learn about the plant. Since the 1920s, marijuana has been illegal on the federal level in the United States and many other countries, which prevents scientists from learning about the drug. This year has been especially insightful for the cannabis industry because many states and countries introduced legislation to legalize the recreational use of marijuana. From all of this progress we’ve made in the cannabis industry, we have learned so much about marijuana in 2017.

An important lesson learned in 2017 about marijuana is that there are no reports of anyone dying from a fatal dose of cannabis alone. Fatally overdosing on marijuana in its most commonly consumed form is seemingly impossible because users would have to consume more than half a gram of pure THC every two pounds of body mass. This would require the average man weighing 195 pounds to consume an ounce and a half of marijuana in one session, which is more than most people consume in their lifetime. Another lesson learned in 2017 is that the demographic of cannabis consumers is growing. Since marijuana has become more legalized, more people have been entering the market, including baby boomers who are now consuming more regularly. Hopefully we will continue to learn more about marijuana in 2018.
