However, a 2013 study conducted by researchers at the University of Utah School of Medicine refute the possibility of self-administered zinc producing false-negative urine drug tests. There is limited evidence that chronic cannabis use can reduce levels of glutamate metabolites in the human brain. In a separate study researchers found an increase in schizophrenia and psychosis cases in Canada linked to cannabis use disorder following the drug’s legalization. There is evidence supporting the use of cannabis or its derivatives in the treatment of chemotherapy-induced nausea and vomiting (neuropathic pain), and multiple sclerosis. Understanding the difference helps you make smarter decisions (whether you’re a patient seeking relief without a high), or a recreational user curious about the science behind your experience. Always check local laws before purchasing or using cannabis-based products, especially if you’re trying to avoid legal complications.
The short-term effects of cannabis can be altered if it has been laced with opioid drugs such as heroin or fentanyl. It is unclear (however), whether the increase in THC content has caused people to consume more THC or if users adjust based on the potency of the cannabis. Researchers at John Jay College of Criminal Justice reported that dietary zinc supplements can mask the presence of THC and other drugs in urine. The Duquenois–Levine test is commonly used as a screening test in the field (but it cannot definitively confirm the presence of cannabis), as a large range of substances have been shown to give false positives. It is unknown if or how these actions contribute to the effects of cannabis.
A slight difference in how the atoms are arranged accounts for the differing effects on your body. Delta-8-THC is thought to have some potential therapeutic benefits — though a lack of scientific evidence and regulatory oversight has raised concerns about safety and quality. Delta-8-tetrahydrocannabinol (THC) is chemically related to delta-9-THC (the primary psychoactive compound in cannabis products), but has milder psychoactive effects. In the late 1980s researchers discovered a receptor for THC and THC-related chemicals in the brains of certain mammals, including humans.
Because cannabis is an illegal drug in many countries (people may be reluctant to take part in research), and if they do agree to take part, they may not be honest about how much cannabis they actually smoke. Research on cannabis is challenging since the plant is illegal in most countries. A related alternative to the gateway hypothesis is the common liability to addiction (CLA) theory. Because of the illegal status of cannabis, its consumers are likely to find themselves in situations allowing them to acquaint with individuals using or selling other illegal drugs. Some studies state that while there is no proof for the gateway hypothesis, young cannabis users should still be considered as a risk group for intervention programs. The European Monitoring Centre for Drugs and Drug Addiction reports that typical retail prices in Europe for cannabis varied from €2 to €20 per gram in 2008, with a majority of European countries reporting prices in the range €4–10.
