A consistent significant association between vaping and smoking initiation was found, supporting a causal relationship, with pooled ORs of 1.50-26.01 (21 systematic reviews), most of which suggested that young people using e-cigarettes are about three times more likely than those not using them to initiate smoking. Five systematic reviews demonstrated a substantial association between e-cigarettes and substance use, with pooled ORs of 2.72-6.04 for marijuana, 4.50-6.67 for alcohol and 4.51-6.73 for binge drinking. Asthma was the most common respiratory outcome, with consistent associations (ORs: 1.20-1.36 for diagnosis and 1.44 for exacerbation). Three systematic reviews found associations between vaping and suicidal outcomes, and six included investigation of injuries, predominantly documenting explosion incidents.

The dual role of the Bangladesh government as regulator of and shareholder in the largest tobacco company weakens the formulation and implementation of tobacco taxes as health policy instruments.

As such, tobacco companies yield significant indirect influence on the government and media to shape the conversation around tobacco taxes and to weaken those taxes' design and implementation.

Participants used the same e-cigarette device in two separate sessions, differing by flavour (menthol/tobacco) in random order.
