The longer a person takes hydrocodone the less sensitive the brain becomes to its effects. As tolerance levels increase, the potential for dependence and addiction grows. These symptoms can reach a point where a person actually starts to “nod out” or experience brief lapses in consciousness as hydrocodone’s sedative effects grow stronger. Users start to have coordination problems, misjudging distances, tripping over things or having problems walking. The drug’s slowing effects soon give way to a noticeably sedated state in cases of hydrocodone abuse. Sedation and fatigue are common signs of hydrocodone abuse. Physical signs of hydrocodone abuse take shape as chemical levels in the brain reach a state of imbalance. These chemicals act as neurotransmitters, enabling different regions of the brain and central nervous system to communicate with one another. The drug’s pain-relieving effects stem from its ability to increase levels of dopamine, serotonin and norepinephrine in the brain. Hydrocodone works by slowing down chemical processes throughout the brain and body. We can help you find the treatment you need to recover. If you suspect you or someone you know may be affected by hydrocodone’s addiction potential, here are 10 signs of hydrocodone abuse you just can’t ignore. Ultimately, hydrocodone’s ability to alter the brain’s chemical balance becomes the driving force behind hydrocodone abuse practices. Contrary to popular opinion, the potential for hydrocodone abuse remains regardless of whether a person takes the drug for medicinal or recreational purposes.
