Switching to Reduced-Nicotine Cigarettes May Aid in Quitting Smoking

Smokers who switch to cigarettes with very low nicotine content may experience mild and transient increases in some withdrawal symptoms. Cigarettes with reduced nicotine will be easier to quit than the cigarettes marketed at present.

E-Cigarettes Promote Smoking Progression in Youth and Depress Quitting Among Adults

E-cigarettes are not an effective tool to reduce combustible-cigarette smoking, two NIDA-supported studies indicate.

Treatment

Cigarette Smoking Increases the Likelihood of Drug Use Relapse

Research suggests that helping patients quit and remain abstinent from smoking may improve their chances for sustained recovery from use of other drugs.

Available Soon: NIDA’s E-Cigarette

NIDA and NJOY, LLC, have developed a Standard Research E-Cigarette. The device will help researchers resolve many outstanding questions about how e-cigarettes affect health.

Prevention Program Reduces Substance Use By Participants' Friends

The Strengthening Families Program for Youth 10-14 (SFP10-14), an evidence-based intervention that reduces teen substance use, also reduced participants’ friends’ substance use. Two factors that accounted for the nonparticipants’ reductions were less time spent by nonparticipants with their participating friends without adult supervision and improvements in nonparticipants’ attitudes toward substance use. The findings suggest that researchers should consider the potential for diffusion of benefits in designing and implementing prevention programs.

Dr. Joni Rutter Q&A: How Basic Science Is Tackling Addiction

One of NIDA’s goals is to try to understand the individual differences that contribute to whether or not someone who takes a drug will become addicted to it. Dr. Rutter’s research focuses on three types of differences: Environmental, developmental, and genetic and epigenetic.

Basic Science

Marijuana Use May Promote Nicotine Consumption

Exposing rats to THC increases the likelihood that the animals will later self-administer nicotine. THC-exposed rats are also willing to work harder to obtain nicotine. When extrapolated to people, the findings suggest that THC’s pharmacological impact on the brain may make a person who uses marijuana more vulnerable to developing nicotine addiction, an underappreciated health consequence of marijuana use.

Intervention Strengthens American Indian Teen Mothers’ Parenting

Teen mothers on three American Indian reservations improved on several measures of parenting after participating in Family Spirit, a home-visiting intervention developed with NIDA support. At 12 months postpartum, the women’s children exhibited reduced rates of emotional difficulties predicting later drug abuse and other behavioral problems. Infants at highest risk—those whose mothers had histories of drug abuse—benefited the most.
