Long-term smokers who switch to vaping ‘see health improve within a month’

A trial which looked at the impact of moving from smoking to vaping found that within a month blood flow through a major artery had significantly improved and was around halfway back to the function of a non-smoker.

So did women - and though it's unclear why, the authors note that "female smokers face more health risks than male smokers do", including greater risks for lung cancer and heart attack.

"Not a single e-cigarette product has been reviewed and approved for sale by the FDA", said Sen.

Separate meta-analysis has shown that for every 1% improvement in vascular health, 13% fewer cardiovascular events occur over the long-term.

British addiction and toxicology experts said last month that the American vaping illnesses were most likely "a US -specific phenomenon", and there was no evidence of a similar outbreak in Britain or elsewhere where the suspect products were not widely used. One group stuck to tobacco cigarettes, the second switched to e-cigarettes with nicotine, and the third switched to e-cigarettes without nicotine. The first is always to consider a reaction to e-cigarettes in someone presenting with an atypical respiratory illness.

He said: "It is crucial to emphasise that e-cigarettes are not safe, just less harmful than tobacco cigarettes when it comes to vascular health". Although quitting smoking is hard, with the average smoker trying 8 times before being successful, the safety of e-cigarettes for smoking cessation needs to be reconsidered, particularly in the era of EVALI.

The same was not true for e-cigarette rates, which increased from about 2.8 percent to 3.2 percent previous year. Within just one month of ditching tobacco for electronic cigarettes, people's blood vessel health had started to recover.

Robertson of the American Heart Association said "the big message ... is that quitting combustible cigarettes is perhaps the most important thing you can do for your health". Advertisements for tobacco cigarettes have been banned from television and radio since the 1970s, but this ban doesn't apply to e-cigarettes. However, while it appears that vitamin E acetate is associated with the patients, evidence is not yet sufficient to rule out other chemicals of concern.

UConn Health's Dr. Mario F Perez, assistant professor of medicine at UConn School of Medicine, has been investigating the dangers of vaping, which is the use of e-cigarettes, since they've been rising in popularity.

Last week, the agency revealed the chemical Vitamin E Acetate could be causing these injuries when it's mixed with THC.

Many brands have taken the products out of their inventories.
