Why the dangers of secondhand smoke could change the innovation

dynamics of the marijuana industry

By Washington Post

Preliminary research presented at the American Heart Association’s

breathing secondhand marijuana smoke might damage your heart

and blood vessels as much as secondhand cigarette smoke, could

impact the trajectory of what, until now, has been primarily a

grassroots marijuana industry. ①在2014年美国心脏协会的科学

会议（学术）上展示的初步报告，内容是吸入二手大麻烟和普通

香烟的二手烟雾对心脑血管的伤害相当，已经冲击了作为大麻产

业的基层产品（大麻烟）。The AHA findings may not significantly

curtail the enormous momentum that the marijuana legalization

movement now has nationwide — where Alaska, Oregon and

Washington, D.C. approved legalizing measures on Nov. 4 — but it

could have important implications for the future structure of the

industry by introducing new risks for smaller businesses.

Until now, the marijuana industry has favored the entry of tiny,

entrepreneurial businesses. This is the result, to a large degree, of

regulatory guidelines that determine who can sell, and how much.

There are other factors as well: the unwillingness of cautious

financial institutions to fund new marijuana start-ups, the bans on

marketing marijuana and the logistical difficulties in distributing

products to a wider audience. Add in the patchwork regulatory

regime that varies by state and the inability of any business to

acquire true scale by crossing over state lines and it means

companies simply can’t scale the way they might in other industries.

As a result, though, we’re seeing rapid innovation in everything

from new products to new business models.

But what happens once there are real legal and health risks involved

as well?

The findings of the secondhand marijuana smoke researchers

suggest that these risks are real and worrisome. What the researchers

found was that blood vessel function in lab rats dropped 70 percent

after 30 minutes of exposure to secondhand marijuana smoke. Even

when the marijuana contained no THC — the active ingredient in

marijuana that produces the ―high‖ — blood vessel function was still

impaired. Reduced blood vessel function may raise the chances of

developing atherosclerosis and could lead to a heart attack, say
