20 questions on medical and recreational cannabis and their impact on the brain.

• Science literacy about cannabis oil benefits is sadly lacking among both the general public and professionals.
• The science of cannabis is more than the botany of the plant. It also involves the neuroscience of the brain’s natural cannabinoid chemistry.
• These 20 questions can test your science literacy about cannabis oil.

Science literacy about cannabis is sadly lacking in both the general public and health professionals. This is not because the public lacks curiosity about the topic, but rather because most people get information about cannabis from friends, the Internet, popular websites, and personal experience — which can be echo chambers filled with anecdotes, opinions, exaggerations, outright misinformation, and a smattering of facts.buy cbd oil.

The cannabis industry opposes warning labels, and the government is prevented by the first amendment from mandating dispensaries provide objective information. Doctors are not well informed about cannabis because as recently as five years ago only 9% of medical schools taught students anything about the use of medical cannabis.[1] These combined influences increase the difficulty of making well-informed, science-based decisions about the proper medical use of cannabis and how to use recreational cannabis safely.

Some questions may seem hard, but all are relevant to a solid understanding of how our brain’s natural cannabinoid chemistry is impacted by THC and CBD. Good luck!cbd oil for sale
