Cocaine primarily acts as a stimulant by affecting the central nervous system, but it doesn't directly inhibit the acetylcholine receptor. Instead, cocaine's main mechanism of action involves blocking the reuptake of neurotransmitters like dopamine, norepinephrine, and serotonin, particularly in the brain's reward pathways.

However, cocaine can have indirect effects on the cholinergic system (which involves acetylcholine) through its overall impact on neurotransmitter balance and neural activity. The cholinergic system can be influenced by the increased levels of dopamine and other neurotransmitters, which may alter the functioning of acetylcholine receptors indirectly.

In summary, while cocaine doesn't directly inhibit acetylcholine receptors, its broad impact on neurotransmitter systems can lead to changes that might affect cholinergic signaling indirectly.
