Yes, they're called cannabinoid receptors.
THC in marijuana attaches to the cannabinoid receptors in the brain, located in close proximity to the receptors regulating appetite.
The ingredient that gives you the feeling of being high is THC. It does that because the THC activates CB1 Receptors in the brain.
No it does not. Your brain does not produce a weed related chemical..... Sorry EDIT: Although the above is correct to an extent, the brain does have natural cannabinoid receptors that have been discovered. These receptors respond to a natural chemical Anandamide (AEA). And don't worry, if there's anything to apologize for it's your lack of information on the subject.
Cannabinoid receptors in the brain can be impacted by drugs like THC (found in cannabis/marijuana) and synthetic cannabinoids (e.g., Spice/K2). These compounds can mimic the effects of natural cannabinoids in the brain, leading to alterations in mood, memory, and perception.
THC receptors in our bodies exist because our bodies naturally produce chemicals that are similar to THC. These receptors help regulate various functions in the body, such as mood, memory, pain, and appetite.
THC, the primary active metabloite in Marijuana binds to the CB1 and CB2 receptors and is an agonist. It prompts the brain to release dopamine and endorphines into your brain, which get you high. Interstingly enough, cannabis contains another cannabinoid, cannbidiol, which acts as a partial agonist to the THC, blocking some of its effects but still letting it chill in your brain. As the cannabidiol is released from blocking the receptors, more THC is absorbed, keeping you high longer. Good cannabis contains around 18-22% THC and a good 35-40% cannbidiol.
What THC does is act on CB1 and CB2 receptors in the brain, which are called cannabinoid receptors. A chemical produced in the body, Anandamide (AEA) is an endogenous cannabinoid that works as a neuroreceptor. It has a negative effect on working memory in lab rats, much like THC. But it also helps reduce sensations of pain, especially when combined with Acetaminophen - acetaminophen is an AEA reuptake inhibitor, increasing circulation of the cannabinoid in the human body, which very likely contributes to its analgesic effects.
I am assuming you are talking about marijuana so..... There are cannabinoid receptors in your brain. THC is a cannabinoid which blocks the receptors, causing dopamine to flood your brain. This is why marijuana highs are associated with a general feeling of well-being. THC affects the sensory and reaction pathways in your brain.
Canabinoids are used within the body in certain areas as neurotransmitters, so yes, your brain does produce chemicals like THC, and employs them in a very controlled fashion, which is quite different from the blunt doping approach that occurs when the naturally occurring equivalents are absorbed into the brain by other means.
THC stores in the organs that contain the most fatty tissue. eg. The reproductive organs (ovaries, testicle's) and the brain.
The main psychoactive component in marijuana that produces the "high" feeling is delta-9-tetrahydrocannabinol (THC). It interacts with receptors in the brain and nervous system to produce its effects.
Delta-9 THC (Tetrahydocannibinol). It alters the receptors in your brain to basically slow down the nerve impulses, which you feel as "high".
