ghostdeini, no bullshit. I don't think we need to thank the bugs for weed... but we sure do need to thank someone for weed. For now it's Mother Nature! Here is an excerpt from Chemical ecology of Cannabis [1994 Netherlands Study]. "Insect predation ... Cannabis is subject to few predators (Smith and Haney 1973, Stannard et al. 1970) and has even been utilized in powdered or extract form as an insecticide (Bouquet 1950) or repellent (Khare et al. 1974). Its apparent defensive mechanisms include a generous covering of non-glandular trichomes, emission of volatile terpenoid substances, and exudation of the sticky cannabinoids. Cannabis is often noted for its aromatic quality and many of the terpenes produced are known to possess insect-repellent properties. Among these are alpha and beta pinene, limonene, terpineol and borneol. Pinenes and limonene comprise over 75% of the volatiles detected in the surrounding atmosphere, but account for only 7% of the essential oil (Hood et al. 1973). Consistent with glandular trichome density and cannabinoid content, more of these terpenes are produced by the inflorescences than the leaves, and their occurrence is also greater in the female plant (Martin et al. 1961). No insect toxicity studies using isolated cannabinoids have been published to date. Rothschild et al. (1977) found THC-rich Mexican (vs. CBD-rich Turkish) Cannabis fatal to tiger moth (Arctia caja) larvae, but not Nigerian grasshopper (Zonocerus elegans) nymphs. Rothschild and Fairbairn (1980) later found that pure THC (vs. CBD) sprayed on cabbage leaves, does repel the large white cabbage butterfly (Pieris brassicae). The cannabinoids may also serve as a purely mechanical defense. A tiny creature crossing the leaf surface could rupture the tenuously attached globular resin reservoirs of the glandular trichomes (Ledbetter and Krikorian 1975) and become ensnared in resin. A sizable chewing insect, if able to overcome these defenses, would still have difficulty chewing the gummy resin, along with the cystolithic trichomes and silicified covering trichomes also present on the leaf. The utility of these epidermal features as insect antifeedants is also inferable from their predominant occurrence on the insect-favored abaxial leaf surface. Although the above strategies represent a seemingly sophisticated system, many other plants (Levin 1973) and even arthropods (Eisner 1970) utilize similar defense mechanisms, often employing identical terpenes!"

Imagine being a tiny bug and finding a trichlome the size of a soccer ball! ![]() OK, if I invent the "honey I shrunk the kids machine" id shrink myself to a insect size person and build a treehouse in my kush plant.
