Two weeks. Mark this.
Not because the hard work is done — it isn't. But because two weeks of abstinence from cocaine represents a real, measurable set of neurobiological changes, and you've earned an accurate accounting of where you stand.
TL;DR: At two weeks of cocaine abstinence, cocaine and its metabolites are fully cleared, the crash phase is long past, D2 receptor upregulation is meaningfully underway, and sleep architecture is beginning to normalize. The challenges ahead: the extinction burst window (weeks 2–4) is still active; post-acute withdrawal syndrome (PAWS) symptoms (mood instability, cognitive fog, low motivation) will be present in varying degrees through month 3; and the complacency window is approaching — the period where recovery starts to feel stable enough that vigilance drops.
What has actually changed
Cocaine is completely cleared. Cocaine itself clears within hours; its primary metabolite, benzoylecgonine, is gone within 3–5 days. At two weeks, there is nothing left of the substance in your system. What remains is the neuroadaptation it produced.
The crash phase is over. The profound dopamine depletion of days 1–3 — the exhaustion, the low mood, the hypersomnia — is fully past. The brain is operating from a different (recovering) baseline.
D2 receptor upregulation is underway. Volkow and colleagues' PET imaging research established that D2 receptor recovery begins in the first week of abstinence. At two weeks, this process is progressing. The improvement in mood floor, the return of some natural reward sensitivity — these reflect genuine receptor recovery.
Sleep is stabilizing. Two weeks of consistent sleep timing has substantially recalibrated the circadian clock. Sleep quality will continue to improve, but the most acute dysregulation is past.
Physical stabilization. Resting heart rate and blood pressure, elevated during the acute period, are normalizing. Energy baseline is more consistent. Physical function is measurably improved.
What's still ahead
The extinction burst. The peak craving window is weeks 2–4. You are in it. The work you did in days 9–10 — understanding the extinction burst, building a craving response plan — applies now.
PAWS. Post-acute withdrawal syndrome (PAWS) refers to the cluster of symptoms that persist beyond the acute withdrawal phase: mood instability, cognitive fog, low motivation, periodic anhedonia, sleep disruption, and episodic cravings. PAWS in cocaine recovery typically runs 3–6 months, with symptoms fluctuating rather than declining linearly. Week 2 PAWS is common and expected.
The complacency window. Research on cocaine recovery identifies weeks 3–6 as an elevated relapse risk period — not because the craving is most intense (the extinction burst peaks earlier), but because the recovery starts to feel stable enough that the urgency fades. When urgency fades, the protective behaviors (the craving response plan, the routine, the social distance) are easiest to abandon. Don't abandon them yet.
Write something down
At day 7, the suggestion was to write about the first week. At day 14, write this: what is different today compared to day 1?
Not in a celebratory way. Factually: what specific things are different? Sleep quality, energy level, mood floor, clarity of thought, time without craving, physical comfort.
This document has two functions. One: it's a record the brain can't quietly rewrite when the Abstinence Violation Effect tries to frame the effort as worthless. Two: it's evidence that the trajectory is real.
You have been here for fourteen days. The changes are real.
What comes next
Weeks 3 and 4 are the complacency and consolidation phase. The series will cover: the complacency window, daily structure, trigger mapping, and the one-month milestone. The work becomes more behavioral and less neurological — which means it requires more active engagement, not less.
You're past the hardest neurochemical week. The behavioral work is next.
