Direct acting cholinergic drugs directly bind to and activate cholinergic receptors, while indirect acting cholinergic drugs increase cholinergic activity by inhibiting the enzyme acetylcholinesterase, which breaks down acetylcholine. Direct acting drugs include bethanechol and pilocarpine, while indirect acting drugs include donepezil and physostigmine.
Some drugs target specific receptors or enzymes in the body, leading to a narrower spectrum of activity. Other drugs may have broader activity by interacting with multiple targets in the body. The specificity of a drug's action is often determined by its chemical structure and mechanism of action.
Blocking acetylcholine receptors can lead to a decrease in cholinergic transmission in the body. This can result in muscle weakness, altered heart rate, and impairments in cognitive function. Blocking these receptors is a mechanism of action for certain medications, such as neuromuscular blocking agents used during surgery.
An example of a substance given to neutralize unwanted effects of drugs is activated charcoal, which can help absorb and eliminate medications or toxins from the body. Another example is naloxone, used to reverse the effects of opioid overdose by blocking opioid receptors in the brain.
Drugs can impact neurotransmitter transmission by either mimicking or blocking the action of neurotransmitters at the synapse. For example, drugs like cocaine can block the reuptake of neurotransmitters like dopamine, leading to increased neurotransmitter levels in the synapse. This alteration in neurotransmitter levels can result in changes in brain function and behavior.
Yes. It makes children think it is right whatever their parents do (which is stupid becaues they're doing drugs.). So yes, it does.

Your brains turn into fried eggs ofc.

ummm, it make them stupid. They make wrong decisions. Drugs fry up your brain cells
They get high from their brains being deprived of oxygen, some drugs cause brain damage in people. Meth can cause holes in people's brains if used over long periods of time.
They block receptors in your brain that cause nausea in the brain.
Therapeutic drugs that block dopamine receptors are most likely to reduce symptoms of psychosis, such as delusions and hallucinations. Blocking dopamine receptors can also help manage symptoms of certain movement disorders, like Parkinson's disease. However, these drugs may also have side effects related to movement, cognition, and motivation.
Depends on the drug used. Certain drugs like marijuana can have little impact whereas drugs such as cocaine and heroin can ruin lives
Scientists have learned a great deal about how THC acts in the brain to produce its many effects. When someone smokes marijuana, THC rapidly passes from the lungs into the bloodstream, which carries the chemical to the brain and other organs throughout the body. THC acts upon specific sites in the brain, called cannabinoid receptors, kicking off a series of cellular reactions that ultimately lead to the "high" that users experience when they smoke marijuana. Some brain areas have many cannabinoid receptors; others have few or none. The highest density of cannabinoid receptors are found in parts of the brain that influence pleasure, memory, thoughts, concentration, sensory and time perception, and coordinated movement.1 Not surprisingly, marijuana intoxication can cause distorted perceptions, impaired coordination, difficulty in thinking and problem solving, and problems with learning and memory. Research has shown that marijuana's adverse impact on learning and memory can last for days or weeks after the acute effects of the drug wear off.2 As a result, someone who smokes marijuana every day may be functioning at a suboptimal intellectual level all of the time. Research on the long-term effects of marijuana abuse indicates some changes in the brain similar to those seen after long-term abuse of other major drugs. For example, cannabinoid withdrawal in chronically exposed animals leads to an increase in the activation of the stress-response system3 and changes in the activity of nerve cells containing dopamine.4 Dopamine neurons are involved in the regulation of motivation and reward, and are directly or indirectly affected by all drugs of abuse.

Taking drugs can impact you in a number of ways. It not only affects your family but it also affects you both mentally and physically.
