The health effects of long-term nicotine use is unknown. [18] It may be decades before the long-term health effects of nicotine e-cigarette aerosol inhalation is known. [19] Short-term nicotine use excites the autonomic ganglia nerves and autonomic nerves, but chronic use seems to induce negative effects on endothelial cells. [20]
[81] [82] Concerns regarding the long-term effects of benzodiazepines have been raised since 1980. [83] These concerns are still not fully answered. A review in 2006 of the literature on use of benzodiazepine and nonbenzodiazepine hypnotics concluded that more research is needed to evaluate the long-term effects of hypnotic drugs. [84]

These side effects are serious and some of them are permanent, and many remain a crucial concern for companies and healthcare professionals and substantial efforts are being encouraged to reduce the potential risks for future antipsychotics through more clinical trials and drug development.
It is speculated that this is due to neurotoxic effects of cannabis interfering with critical brain development. [16] [17] Chronic use of cannabis during adolescence, a time when the brain is still developing, is correlated in the long term with lower IQ and cognitive deficits.
The long-term effects of benzodiazepines are still not fully understood. Long-term benzodiazepine use is associated with attentional and visuospatial functional impairments. Withdrawal from benzodiazepines can lead to improved alertness and decreased forgetfulness in the elderly. Withdrawal led to statistically significant improvements in ...
