Melatonin vaping may help some people with sleep problems, but the research on its effectiveness is limited. Melatonin supplements have been widely studied and have been found to be effective in promoting sleep in some people with insomnia or other sleep disorders. However, there is limited research on the use of melatonin in vapes specifically, and more research is needed to determine its effectiveness and safety.
It's also important to keep in mind that melatonin is not a sleep aid and should not be used as a substitute for good sleep hygiene and healthy sleep habits. If you are having trouble sleeping, it's best to talk to a doctor or a sleep specialist who can help determine the cause of your sleep problems and recommend appropriate treatment options.
