Think vaping is harmless? Think again. Short term side effects include coughing, throat irritation, asthma flare ups, and even seizures or heart issues. Long term effects can include chronic lung disease, impaired lung development, and I also learned there's a vape pen out there shaped like an asthma inhaler. You can also suck on one that looks like a reusable coffee cup. Flowrite Vape Asthma Inhaler :: Behance Smyle Labs Inhaler Vape Smart.com
