This pot loving hippy bullshit has to stop. If you smoke pot, you're a fucking pussy. Even if it's legal, you're still a disgusting excuse for a human if you have to use medication for an illness you don't have. Don't give me that "muh seizures" bullshit. You wouldn't receive chemotherapy if you didn't have cancer and you don't need pot of you don't have some kind of severe grand mal seizures. Fucking pussies, the whole lot of you.

Right never mind those receptors in your head made solely for recieving cannabis. Go drink another one pal.

The form and function concept is very prevalent in biological systems. Because tetrahydracannabinol closely resembles endogenous ligands of the endocannabinoid system, it may exploit a currently existing physiological response. What we are bearing witness to is a biological arms race. Nicotine is a compound produced by plants that binds with the nicotinic acetylcholine receptors in humans. This receptor did not evolve for the sole purpose of binding nicotine. Nicotine can function as a pesticide, which is what I mean by a biological arms race. Humans are much more resilient to the effcts of nicotine, so a similar size dose that would act as a pesticide for insects is not fatal to humans but induces effects that may be considered desirable or enjoyable. The same thing goes for caffeine.

So, if a ligand binds with a receptor, does that mean the receptor's sole purpose for existence is to bind that specific ligand?

Let's consider aspartame. It is a synthetically engineered compound that consists of modified, natural amino acids that mimic the shape of a saccharide. The shape allows aspartame to bind with sensory receptors of the tongue in order to induce the sensation of sweetness similar to a saccharide. The body metabolizes saccharides and amino acids differently so the theory is that you get the same same taste sensation without the fattening side effects although recent evidence suggests aspartame could be carcinogenic in certain doses. Regardless, it is very clear to see that the taste bud receptors did not evolve specifically to bind with aspartame. It is simply an exploitation of their biologically relevant function to identify compounds that are beneficial to the organisms overall metabolic needs.

Let us also consider malaria. The Duffy Antigen is a receptor that binds with malaria and allows the invasion of the parasites into the host's erythrocytes. The Duffy Antigen is a common medical name for a chemokine receptor. Chemokines are signalling molecules that are important regulating facors in immune responses, cell growth and differentiation, and angiogenesis. So woud the existence of this receptor mean that humans are supposed to ingest malarial parasites? I think not.

Your line of reasoning is akin to the "banans are made by god" logic that neglects the billions of years of natural selection and more recent centuries of artificial selection that have led to the horticultural achievement of the modern banana.

Furthermore, there is a logical fallacy that organisms evolve with a purpose and a direction. There is no direction to evolution. The compatability of a ligand and a receptor are the result statistical probabilities. The compatability does not imply that they evolved with the sole purpose of complementing one another.

The notion that ligand-receptor compatability is evidence of a predetermined relationship between the two constituents is an erroneous assumption that parallels religious fanatacism.

edit: spelling

edit: It is important to note that the receptors to which you are referring do not solely bind the psychoactive component of marijuana. These receptors bind a hole host of endogenous cannabinoid compounds that are naturally present in humans. Endocannabinoids are not psychoactive.

As someone who has free access to legal Jew's Cabbage, I can tell you I've never had any desire to start using opiates.
