That evidence is confusing tobacco smoke with commercial cigarette smoke. This drives me crazy, and the evidence I've compiled in all my posts supports this. The evidence is obvious and overwhelming from my perspective.
599 chemicals added to commercial cigarettes. Arsenic, cyanide, formaldehyde, DDT, etc. When the cigarette burns the chemicals break apart forming over 7,000 mostly toxic/carcinogenic chemicals emitted. 90% of tobacco in the US is genetically modified so they can survive higher levels of pesticides. Since the 40's, they have been fertilizing the tobacco fields in the US with radioactive fertilizers. Because of this, in a years time the average smoker received the equivalent of 250 chest X-rays worth of radiation. Commercial cigarettes only contain 25% non-filler tobacco.
Cigarette manufacturers now put "ethylene vinyl acetate copolymer" (carpet glue) adhesive into the paper of the cigarettes. Smoking glue. The self extinguishing cigarettes produce 13.9% more Naphthalene and 11.4% more carbon monoxide. Naphthalene in quantity, causes nausea, vomiting, diarrhea, confusion, anemia, jaundice, convulsions and coma."
Nicotine and the beta-carbolines/ tobacco is a medicine. Lowers blood pressure, anti-depressant, anti-tumor, anticholinesterase (AChE) inhibition. (Inhibits of the enzyme that breaks down choline/acetylcholine in the brain. These are naturally occurring endogenous neurotransmitters which increase cognitive function. Increasing cholinergic neurotransmission in various regions of the brain can also result in increases of various catecholamines (dopamine, epinephrine, norepinephrine) in the post-synaptic space. Acetylcholine esterase inhibitors have been shown to increase REM sleep.
Syrian alkaloids include β-carbolines, such as harmine, harmaline, harmalol, harman, harmalidine, ruine, and tetrahydroharmine, and the quinazoline derivatives vasicine (peganine) and vasicinone. Effects of these, including abortifacient, antibacterial, anti-cholinesterase, antileishmanial (acts against Leishmania parasites), antimicrobial, antinociceptive (reduces sensitivity to painful stimuli), antiplasmodial (counters parasites of the genus Plasmodium), antiprotozoal, antiseptic, antitumor and antiviral. Harmala seeds have been used in traditional medicine as an emmenagogue, analgesic, and anthelmintic (antiparasitic/expels parasitic worms and other internal parasites from the body by either stunning or killing them and without causing significant damage to the host), a galactagogue, and a a remedy for brain or nervous problems, stomach complaints, jaundice, and lumbago. Tobacco which contains β-carbolines, would share a lot of these benefits. Tobacco is known to be effective against parasites. And has been traditionally used as an analgesic by Native Aericans.
Nicotine activates orexin neurons. Nicotine increases both Orexin A and B and ALSO increases orexin receptors. Nicotine and orexin excite the same synapses of the arousal pathway within the prefrontal cortex (thalamocortical). So it increases wakefulness independently by activating the same neural pathways.
Not to mention and look at the shared mystical/metaphysical and highly sacred beliefs of the native cultures regards for the tobacco plant.
If look at this evidence from a logical perspective, it should be obvious that the tobaccco plant is a completely different thing tan commercial tobacco products and these products are poison.
