Ive smoked RY4 from smokeless image for almost 5 years. Never went to anything else.. It worked and I didnt think anything else about it up until about 3 weeks ago. Ive always been a mouth to lung smoker with the vape pen from smokeless image. Now 3 weeks ago I changed to a vaporesso target pro. The flavors tasted great and I was getting huge clouds (something I never really desired for in the past) So I landed on Liquid States Cali Colada. A juice that is 80% VG. I fill my tank up probably 3 times a day now. The last few days Ive had the "heavy lung" thing going on I guess. Do you guys think the juice is the cause? I will say since I changed to the new vape. I rarely do a mouth to lung hit, they are pretty much straight lung hits now...
