After the nicotine is gone, and the brain stops releasing the positive neurotransmitters, smokeless tobacco users feel tired, depressed, and down. Nicotine also causes the brain to release a chemical called dopamine. Other very addictive drugs like cocaine make the brain release dopamine, too.
The short acting form of Adderall is taken by patients twice a day in tablet form. The recommended starting dose for children 3 to 5 years of age 2.5 mg daily; children 6 years or older is 5 mg once or twice daily. Depending on the individual, an adultâs usual dose is 5 mg to 60 mg daily.
Best Answer: You're absolutely right. Immediate-release Adderall takes affect immediately, within 15-30 minutes. 2.5mg is just your starting dose (yeah, it is a tiny dose). You're doctor will most likely increase your dose after a week or month.
