You’ve got to remember they already make lots of money selling Nyquil and other remedies for colds and flus.
And I’ve never heard of that type of pot, but smoking it will surely exacerbate a cough.
Neti pot-you fill it with saline for a sinus wash-it isn’t a bong...
You have a good point, since Nyquil and that other stuff aren’t remedies per se-they relieve symptoms of the cold or flu, but don’t do a thing to shorten or cure the malady. Based on that, the manufacturers of those “remedies” certainly wouldn’t want something on the market that would diminish the need for their products by the consumer.
