In 2009 32,000 people died from adverse reactions to prescription drugs. 7,600 died from non-steroidal anti-inflammatory drugs such as aspirin. 85,000 people lost their lives to alcohol abuse.
There is no known documentation of a death caused by a cannabis overdose. Ergo, cannabis is safer than aspirin.
After a brief contemplation it dawned on me I should clarify my statement about cannabis being safer. I’m talking from a purely medicinal (or recreational) stand point.
You see, I know of no one that’s been the victim of a home invasion because the robbers were after the aspirin (sigh).
