While tobacco use occurs in many forms all over the world, there is little information on cross-tobacco use. Authors report an unusual case of tobacco use in the form of chewing beedies which are normally smoked (cross-tobacco use). A 22-year-old single female, diagnosed with schizophrenia for the last 6 years, started chewing beedies from the age of 15 years and was using it in a dependent pattern since 7 years. After 3 years of treatment for her schizophrenia, patient's family pressured her to seek tobacco cessation treatment. Initial treatment with nicotine gum replacement and behavioral counseling did not prove useful. Subsequently she was treated with bupropion 300 mg/day and able to successfully abstain. Cross-tobacco use is relatively rare, and merits further study, especially in the mentally ill population.

Betel quid contains two major ingredients; Areca catechu and Piper betel, often consumed with slaked lime, tobacco, certain flavouring agents, colouring agents, herbs, and spices according to personal preferences. The areca nut alkaloids (arecoline, arecaidine, guvacine, and guvacoline), and tobacco alkaloids (nicotine, nor-nicotine) undergo nitrosation during chewing in the oral cavity with the presence of nitrite and thiocyanate and endogenously. Among the nitrosation products generated areca nut-derived nitrosamine (ADNA): 3-(methylnitrosamino) Propionitrile (MNPN) and the two tobacco-specific nitrosamines (TSNAs); N'-nitrosonornicotine (NNN) and 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone) (NNK) are considered Group 1 human carcinogens.

Background: Smokeless Tobacco (SLT) use prevalence among youth in the United States (US) is comparable to youth prevalence of cigarette smoking. However, it is in general understudied compared to cigarettes and draws less attention nowadays compared to e-cigarettes (ECs).
Aim: We estimate the own- and cross-tax elasticities of SLT use among US youth and explicitly test how SLT use changes in response to taxes on SLT, cigarettes, ECs, and beer.

Background: States adopt different tax bases for smokeless tobacco (SLT), making tax incidence on SLT not directly comparable across states. In addition, how taxes are passed through to SLT prices among states that impose specific taxes, and whether the pass-through rates for SLT are affected by the uptake and evolution of e-cigarettes, is unknown.
Objective: This study will calculate the tax incidence on SLT and investigate how SLT taxes are passed to prices at the 25th, 50th, and 75th percentile levels, as well as whether these pass-through rates vary by e-cigarette uptake and evolution.
