Are the possible bronchial dilation side-effects of adderall (dextroamphetamine and racemic amphetamine) (amphetamine) long-lasting, or will they likely diminish with regular use?

Diminish: Tolerance develops with chronic exposure. Use a rescue inhaler every day and it loses its effectiveness. Take an amphetamine every day and its 'side effects' diminish. That includes both bronchodilation and the stimulant effect of adderall (dextroamphetamine and racemic amphetamine). If bronchodilation is uncomfortable, talk to your doc and try a lower dose. Adhd + ptsd means you need a psychiatrist to manage this.
