Researchers exposed rats to smoke or aerosol from tobacco cigarettes, JUUL e-cigarettes, IQOS heated tobacco products, marijuana cigarettes and cannabinoid-depleted marijuana cigarettes.
Some exposures affected heart function after a single session, while repeated exposure increased platelet activity and was associated with greater heart-tissue damage after an experimentally induced heart attack. These findings come from rats and require human research for clinical interpretation.

View Original SourceDifferent tobacco and inhaled products can expose the cardiovascular system to substances other than nicotine alone.
Animal studies can help researchers understand possible biological mechanisms, but they cannot by themselves establish the level of cardiovascular risk in people.
Research comparing cigarettes, e-cigarettes and heated tobacco can help build evidence about whether different inhaled products affect the cardiovascular system in similar or different ways.
Public health decisions should use the wider body of human and experimental evidence rather than relying on one animal study.
اس تحقیق میں چوہوں کو عام سگریٹ، جول ای سگریٹ، آئی کیوس ہیٹڈ ٹوبیکو اور ماریجوانا کے دھوئیں یا ایروسول کی نمائش دی گئی۔ کچھ مصنوعات کی ایک مرتبہ نمائش کے بعد دل کے کام میں تبدیلی دیکھی گئی، جبکہ بار بار نمائش سے خون کے پلیٹ لیٹس کی سرگرمی بڑھی۔
بار بار نمائش کے بعد تجرباتی طور پر دل کا دورہ پیدا کیے جانے پر دل کے ٹشو کو زیادہ نقصان بھی دیکھا گیا۔ تاہم یہ تمام نتائج چوہوں پر کیے گئے تجربات سے ہیں، اس لیے انسانوں کے خطرے کے بارے میں حتمی نتیجہ نکالنے کے لیے انسانی تحقیق ضروری ہے۔
