Nicotine and cannabis are often used together, especially by young adults. Combined use may enhance addiction and anxiety relief but poses risks like cognitive impairment and weight gain.
Area of Science:
- Neuroscience
- Pharmacology
- Addiction Research
Background:
- Nicotinic and cannabinoid systems are key targets for widely used drugs of dependence.
- Combined use of nicotine and cannabis is prevalent, particularly in adolescents and young adults.
- Understanding interactions is crucial due to increasing co-use and addiction concerns.
Purpose of the Study:
- To review the interactions between nicotine and cannabis, focusing on addiction.
- To explore addiction theories, therapeutic implications, and adolescent use patterns.
- To examine effects on anxiety, food intake, and cognition.
Main Methods:
- Literature review of pharmacological interactions between nicotine and cannabis.
- Analysis of studies on addiction, gateway theories, and adolescent development.
- Examination of research on anxiety, appetite, and cognitive functions.
Main Results:
- Joint nicotine and cannabis consumption may enhance reinforcing and anxiolytic effects.
- Contrasting effects on cognition exist, with cannabis potentially causing long-lasting impairments.
- Adolescent use presents unique risks, with emerging sex differences.
Conclusions:
- Combined use of nicotine and cannabis may increase dependence potential.
- Adolescent cannabis use raises concerns about cognitive deficits and weight gain.
- Further research is needed, especially regarding sex differences in adolescent users.

Drugs Acting on Autonomic Ganglia: Stimulants
Ganglionic stimulants activate NM nicotinic receptors in autonomic ganglia, falling into two categories: nicotine mimetics [e.g., lobeline, dimethylpiperazine, tetramethylammonium] and muscarinic receptor agonists [e.g., muscarine, methacholine]. The first category's action is rapid and blocked by nicotinic receptor antagonists, while the second category's action is delayed and blocked by atropine-like agents. Nicotine, an alkaloid, affects the heart rate by stimulating sympathetic or...
