Asthma Cigarettes

These are Kellogg's asthma cigarettes (containing stramonium!) from 1968. The Datura Stramonium plant is a member of the nightshade family (it is also known as jimsonweed or devil's snare) and smoking stramonium is known to relive asthma symptoms. It is also a powerful hallucinogen and delirient, which is a clinical term meaning it causes fully formed and extremely unpleasant visions and delusions. In just slightly higher doses it is fatal so "careless use often results in hospitalizations and deaths". Consider this a public service announcement in these times of trump & ford.
