What is Meth? The drug, Nick Reiner was addicted to, which kept him awake for days

Nick Reiner's alleged descent into violent behavior was reportedly fueled by a severe addiction to methamphetamine, according to the Daily Mail. Sources claim the 32-year-old would use meth and then go without sleep for days, a dangerous condition known as "tweaking." This state forces the brain to stay awake chemically, which can lead to hallucinations, extreme irritability, and a complete loss of impulse control.

Methamphetamine is a powerful stimulant that affects the central nervous system. Unlike depressants such as alcohol or heroin, meth causes the brain to release large amounts of dopamine, creating intense energy and preventing the body from sleeping for extended periods. Sources speaking to the Daily Mail indicated that Nick Reiner would regularly "do meth and not sleep for days." In addiction terms, this is known as “tweaking,” a perilous phase characterized by 3–15 days of sleeplessness. During this time, users may experience hallucinations and become unpredictable, irritable, and prone to violent paranoia.

The guest house on Rob Reiner’s Brentwood property became the location of Nick’s outbursts. Insiders described violent episodes during these sleepless binges, during which he would lose control, "breaking things" and "punching walls." Nick himself acknowledged this behavior in a 2018 interview on the Dopey podcast, recalling a time when he was "spun out" and started "punching out" appliances in a confused state.

Reportedly, friends and family lived in fear of his next outburst. One source described Nick as a "ticking time bomb" whose behavior had become increasingly erratic over the past five years. Despite living in a luxurious environment, his proximity to his parents became a source of terror rather than comfort. Rob and Michele Reiner reportedly wanted him "out of their hair" for their own safety.

Sources also allege that Nick’s reaction to the destruction he caused was particularly disturbing. After allegedly destroying the guest house "more than once," he would often laugh at the chaos or act "nonchalant about it." This apparent lack of remorse or embarrassment, which could be a symptom of long-term stimulant abuse, suggested a significant detachment from reality and the consequences of his actions.

Rob and Michele Reiner reportedly made several attempts to help their son. The report states that they issued an ultimatum: "Take medication and stop using, or move out." They also threatened to call the authorities on multiple occasions but hesitated, hoping that rehab would be effective. Nick, who had been to rehab "more than a dozen times," reportedly refused further assistance, dismissing support groups as "too cultish."

The violence was not limited to property damage. The situation is said to have escalated when Nick’s sister (likely Romy or Tracy) confronted him about his addiction. Sources claim Nick threatened her, leading to a major conflict. This incident highlighted the growing danger he posed to the entire family, not just his parents.

The tragic culmination of this "meth-fueled" situation occurred this past weekend. Nick was reportedly "calmly strolling away" from the home, while his parents were found dead inside. Authorities discovered Rob and Michele in a state of rigor mortis, suggesting they had been dead for several hours, raising the possibility that a final, sleepless episode turned the "ticking time bomb" into a double murderer.
