For starters, ailments in Ayurvedic medicine are diagnosed merely by examining one’s pulse . Examining the pulse is good for precisely that, finding out heart rate (which can be indicative of a handful of things ), but the Chopras of the world claim it can diagnose almost everything , including spiritual inclination, menstrual problems, blood disorders, and constipation. This has never been replicated in a laboratory setting. Furthermore, some Ayurvedic treatments have been shown to contain lead and mercury .

Cannabis smoke contains thousands of organic and inorganic chemical compounds. This tar is chemically similar to that found in tobacco smoke,  and over fifty known carcinogens have been identified in cannabis smoke,  including; nitrosamines, reactive aldehydes, and polycylic hydrocarbons, including benz[a]pyrene.  Light and moderate use of cannabis is not believed to increase risk of lung or upper airway cancer. Evidence for causing these cancers is mixed concerning heavy, long-term use.
