At this time, it is not possible to predict which teens will experience these additional conditions. It is likely that genetics play a role. The additional stresses experienced by teens with ADHD, such as social criticism or internal frustration, may also make teens more vulnerable to these difficulties. For more information on these co-occurring conditions, please see ADHD and Co-existing Conditions . If you suspect that your teen may have any of these additional conditions, consult a psychologist, psychiatrist, or other clinician with expertise in ADHD to have an assessment.
While a psychotic reaction can occur following any method of use, emergency room responders have seen an increasing number of cases involving marijuana edibles. Some people (especially preteens and teens) who know very little about edibles don't realize that it takes longer for the body to feel marijuana’s effects when eaten rather than smoked. So they consume more of the edible, trying to get high faster or thinking they haven't taken enough. In addition, some babies and toddlers have been seriously ill after ingesting marijuana or marijuana edibles left around the house.
Primary sex characteristics are those directly related to the sex organs . In males, the first stages of puberty involve growth of the testes and scrotum, followed by growth of the penis.  At the time that the penis develops, the seminal vesicles , the prostate , and the bulbourethral gland also enlarge and develop. The first ejaculation of seminal fluid generally occurs about one year after the beginning of accelerated penis growth, although this is often determined culturally rather than biologically, since for many boys first ejaculation occurs as a result of masturbation.  Boys are generally fertile before they have an adult appearance.
