The symptoms of one quarter of these users were partially attributed to cannabis (a total of 2567 out of 449,031 patients); other drugs were sometimes involved. Of these cannabis admissions, one quarter were for acute psychiatric effects, primarily suicidal ideation, depression, and anxiety. An additional third of the cases were for gastrointestinal issues including Cannabinoid hyperemesis syndrome.According to the United States Department of Health and Human Services, there were 455,000 emergency room visits associated with cannabis use in 2011. These statistics include visits in which the patient was treated for a condition induced by or related to recent cannabis use. The drug use must be "implicated" in the emergency department visit, but does not need to be the direct cause of the visit. Most of the illicit drug emergency room visits involved multiple drugs. In 129,000 cases, cannabis was the only implicated drug. Reproductive health
There is sufficient evidence of reproductive health harms from cannabis that its use when trying to conceive, during pregnancy, and while breastfeeding, is not advisable.It has been recommended that cannabis use be stopped before and during pregnancy as it can result in negative outcomes for both the mother and baby. However, maternal use of marijuana during pregnancy does not appear to be associated with low birth weight or early delivery after controlling for tobacco use and other confounding factors. Pharmacology
Mechanism of action
The high lipid-solubility of cannabinoids results in their persisting in the body for long periods of time.
In this unfamiliar environment, the child may find the pressure to rapidly adapt and fit in. Children start to spend less time with family and more time with friends. At this time, socialization by the school and peer environment can become more predominant, as the preadolescent starts to learn more about how they would wish to hold themselves during interpersonal relationships.While children find this need to fit in, preadolescents have a conflicting desire to establish their own individualism. As the child grows into the transitionary period of preadolescence, the child often starts to develop a sense of autonomy as the child is exposed to a larger world around them full of sudden and unfamiliar changes. Compounded with a sense of self-consciousness, the preadolescent starts to explore their own self-identity and their role in society further. Development of sexual orientation
During preadolescence (early adolescence), individuals may become more preoccupied with body image and privacy, corresponding to physical changes seen during adrenarche and puberty. Early adolescents may become aware of their sexuality for the first time, and experience attraction towards others. Homosexual and heterosexual experimentation is not uncommon, although it is important to note that many teens who eventually identify as LGBT do not always do so during adolescence. On average, gay, lesbian, and bisexual individuals report experiencing same-sex attraction in early adolescence, at age 12. About 4 in 10 gay men, and 2 in 10 lesbian women report experiencing same-sex attraction before age 10.
