Smoking nutmeg has numerous side effects, including nausea, vomiting, high blood pressure, drowsiness, heart palpitations, body ache, convulsions, depression and respiratory depression, according to Drug Addiction Help. Other side effects include hallucinations and delirium.
Inhaling nutmeg also causes a wide variety of side effects, including euphoria and hallucinogenic experiences that are similar to those experiences when using LSD, reports Drug Addiction Help. Many users have said the side effects of smoking nutmeg are so bad that they're not worth any high they can achieve with smoking or inhaling nutmeg. The side effects of smoking nutmeg can last for a few days and, when used in large amounts, can cause overdose, poisoning and even death.
