People are rightly criticizing this study, but for the wrong reasons. 1. There is no establishment of causality, but the article pretends there is. People who use marijuana may use it because they have high-stress lives. 2. It only applies to smokers. About 70% of the marijuana products at the dispensaries I've been to are not meant to be smoked. To quote the original article ['Recreational marijuana is primarily smoked; we hypothesize that like cigarette smoking, marijuana use will be associated with increased cardiovascular mortalities'] 3. No link to original study. [I think it's this: http://journals.sagepub.com/doi/pdf/10.1177/2047487317723212 http://journals.sagepub.com/doi/pdf/10.1177/2047487317723212] 4.

This could be because marijuana smokers are more likely to take drugs that do change blood pressure.
