Hi Dr. Dressler. Some great information. I have one question regarding fish oil…is there a distinction between cod liver oil and fish oil. As in, isn’t cod liver oil just a specific type of fish oil? I have that and am giving it to my 3 yo Goldendoodle (we’ve known about his GI lymphoma for less than a week, so this is all new to us). Currently 1 tsp (the liquid type) a day with plans to begin increasing it. I just read your post regarding krill, so it got me thinking. I thought that perhaps others would be interested as well to know if “fish oil is fish oil is fish oil,” for omega-3 purposes, of if there are distinctions in type (beyond what you’ve written about krill) or other dangers.
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. In general there are far lower risks of pulmonary complications for regular cannabis smokers when compared with those of tobacco.  Combustion products are not present when using a vaporizer , consuming THC in pill form, or consuming cannabis foods .
