In India, the legality of dry herb vaporizers is unclear. While no specific law prohibits their use or possession, the sale and use of drugs, including marijuana, is prohibited in India. However, there has been a growing movement in the country to legalise medical marijuana. The use of dry herb vaporizers for medical purposes may be permissible in some cases, but the legal landscape surrounding their use is complex and subject to change. To determine the current state of the law in your area, it is always best to consult with local authorities or a lawyer.
