Do not, DO NOT, EVER, attempt to make your own cigarettes.....
During my National Service to my Nation, in survival training on an isolated island, as in such a course, we were only allowed our uniforms and nothing else, not even a matchstick, and were thoroughly CHECKED for any other items. hidden as we tried, but there was a habitual smoker who knew what kind of dried leaves to use to use for smoking.
He selected the necessary dried leaves, rolled it into a stick, using sticks and stones to light a fire to light his cigarette, and simply puffed away. The insignificant nobody me happened to chance upon his dwelling while searching for food, isolated as each were in that landmass, and he offered me puff on his self made cigarette.
I took a puff, and it KNOCKED me out with just one puff......nicotine comes from alkaloids, from such leaves, and needs to be treated chemically in order to be safe for Human consumption...but those UNTREATED burning leaves produces FAR FAR more stronger alkaloids.....
