Depending on the details of the particular carbon trading scheme, Oil, gas and coal companies would either have to purchase emissions credits themselves, or would likely have to lower the price of their products, as customers would have to purchase allowances to cover the carbon dioxide emissions released by their use.
Traditional NSAIDs include aspirin, ibuprofen (Advil, Motrin, etc.), naproxen (e.g., Aleve), and many other generic and brand name drugs. Celecoxib (Celebrex) belongs to a newer class of NSAIDs, which doctors call a âCOX-2 inhibitor,â and is designed to avoid upset stomach.
Because it inhibits both COX-1 and COX-2, aspirin is considered a non-specific NSAID. Other non-specific NSAIDs include ibuprofen, naproxen, and indomethacin. However, aspirin is distinct from these other non-specific NSAIDs because its inhibition of the COX enzymes is irreversible.
