Marijuana is becoming legal in many states. But it is not without some potentially dangerous effects; just as alcohol has. Using these mind-altering drugs must be done in moderation and care.
In a recent study (https://doi.org/10.1177/2047487317723212) in European Journal of Preventive Cardiology researchers found that among 1200 participants there was a 2-3 times increased risk of death related to high blood pressure among users.
In another study, researchers looked at marijuana's effects on anxiety and stress (Drug Alcohol Depend 2017 May 30). It is approved for PTSD and chronic anxiety. In this report they found that, in normal volunteers, a higher dose (12.5mg) increased depression, anxiety, and confusion; while the lower dose 7.5 mg actually decreased anxiety. It is important to be aware of this possibility if you take marijuana for medical reasons, and of the side effects tht can occur with recreational use.
Finally, British researchers did a 30 year study on the effects of alcohol on the brain. They found that levels equivalent to 1 glass of wine a day had no effects; but increasing levels, up to 2 glasses a day, was associated with a 3-6 times amount of decrease in brain mass (in the memory centers) when compared to non-drinkers.

As usual moderation is the key, and knowing the possible effects of our recreational drugs is important!
