Recently, I read that in the United States there has been a significant increase in THC use in recent years. Along with this, a phenomenon known as Cannabinoid Hyperemesis Syndrome (CHS) has been appearing more frequently.
THC, which many perceived as a beneficial, calming, or medicinal substance, has in some cases turned into an opponent.
THC often acts as a means of inducing euphoria, relieving various types of pain, and improving appetite. However, in some cases—especially with chronic use—it transforms into the opposite of what it was meant to provide.
Cannabinoid Hyperemesis Syndrome (CHS) is precisely that opposite, and it appears to occur in many chronic THC users.
From experience, I have encountered this in certain individuals as well. They often appear tired, weakened, lacking appetite, frequently vomiting—yet they continue using THC, believing they will overcome the condition, or perhaps due to a perceived dependence. This is cannabinoid hyperemesis syndrome.
I looked into
the reasons behind CHS:
The endocannabinoid system is a part of the human body—it regulates mood, appetite, stress, and pain perception. When this system is stimulated externally over a long period of time, it adapts. It reduces sensitivity. It recalibrates. It searches for a new balance: The paradox is that the more a person tries to stabilize their experience through an external substance, the more they may disrupt the body’s ability to stabilize itself.
What is striking is the cyclical nature of this phenomenon: Nausea → THC use → short-term relief → deeper destabilization → further use.
The body sends a signal, but the mind interprets it through past experience: “This has always helped me.” And it is precisely this memory of relief that sustains the cycle.
Physical exhaustion, dehydration, and loss of strength during CHS episodes are symptoms. The body loses electrolytes, cannot eat, sleeps poorly. The body is under strain. Psychological apathy, irritability, or anxiety when abstaining point to another kind of dependence—not necessarily dramatic, but quiet: dependence on external regulation of one’s internal state. The user may find themselves in a vicious circle, aware that THC no longer benefits them, yet unable to stop using it.
The phenomenon of CHS is not merely a medical complication. It is a reminder that any long-term artificial amplification or suppression of a system changes its fundamental setting.
Not every long-term cannabis user will experience this condition. Reactions are individual. Genetics, frequency of use, THC potency, and nervous system sensitivity all play a role. But for those in whom this cycle develops,
the solution…
is paradoxically simple—though psychologically demanding: complete cessation for at least an extended period of time. A return may be possible, but likely only in the form of occasional use rather than chronic use.
