Is smoking on the rise or decline?

Adult smoking rates dropped from 42% in 1965 to 14% in 2019, according to Centers for Disease Control and Prevention.

Why is smoking increasing?

The increase during 2017-2018 was primarily driven by an increase in e-cigarette use among young adults (18-24 years old), which rose from 5.2% in 2017 to 7.6% in 2018. Smokeless tobacco use also increased from 2.1% to 2.4% among adults during the same time period.

What does smoking do to INR?

While there is a paucity of data to determine the clinical impact of smoking on warfarin, it is proposed that hydrocarbons in cigarette smoke induce CYP1A2, CYP1A1, and CYP2E1. The induction of these enzymes creates the potential for an increase in the concentration of warfarin, thus leading to an increase in INR.

Does nicotine affect INR?

If the addition of smoking increases warfarin metabolism and clearance, then smoking cessation would lead to a decrease in warfarin metabolism and clearance that would result in higher INR values. Multiple cases have been reported in the medical literature to support this effect.

Does smoking affect DVT?

Can you smoke cigarettes on blood thinners?
