As a symphony musician and a biomedical researcher who studies the effects of secondhand smoke on the cardiovascular system, I was dismayed to read about the Colorado Symphony Orchestra's plan to perform a series of bring-your-own-marijuana concerts sponsored by the cannabis industry. There is no reason to believe that marijuana smoke, including secondhand smoke, is less harmful than tobacco smoke. Regardless of the nicotine, both kinds of smoke contain thousands of chemicals, many of which are carcinogens, and smoke from sources other than tobacco cigarettes can still cause rapid harmful effects on the heart and blood vessels. To encourage audiences to be exposed to secondhand smoke is irresponsible and disrespectful of their health needs. If the CSO wishes to increase its audience base, the last thing it should do is to increase audience members' chances of heart attack and stroke. Matthew L.
