Urine Drug Testing – Cocaine & Methamphetamine (MA)
Scope
This page covers typical urine detection windows for cocaine and methamphetamine (MA), including chronic-use scenarios. Times assume standard lab immunoassay cut-offs.
Cocaine
What is detected:
• Benzoylecgonine (main metabolite)
• Cocaine itself clears very fast
Detection window (urine):
• Single / occasional use: 2–3 days
• Heavy or repeated use: 5–7 days
• Extreme binges (rare): up to 10–14 days
Notes:
• Cocaine has one primary metabolite
• Short-lived compared to stimulants like MA
• Most users are clear within 72 hours
Methamphetamine (MA)
What is detected:
• Methamphetamine
• Amphetamine (active metabolite – this is the limiter)
Detection window (urine):
• Single / light use: 2–4 days
• One-day heavy use: 4–6 days
• Multi-day binge (2–4 days): 6–8 days
• Chronic / high-dose use: 8–10 days
• Outliers (daily, long-term use): up to 14 days
Why MA lasts longer than cocaine:
• Converts to amphetamine
• Amphetamine accumulates with repeated use
• Chronic use causes metabolite stacking
Route of Use
• IV / smoked: slightly longer tail
• Nasal: middle
• Oral: slightly shorter
Frequency and total dose matter far more than route
Urine pH & Hydration
• Alkaline urine = slower excretion
• Acidic urine = faster excretion
• Labs account for dilution; hydration does not “cheat” tests
Rule of Thumb
• Cocaine: usually clear in ≤3 days
• MA single use: ~3–4 days
• MA binge: ~7 days
• MA chronic: 10+ days possible
Important:
Long detection times are driven by chronic daily use without breaks, not isolated doses.

Does anyone know where I can get an at home urine test for Hydromorphone?
-
I found several including from Amazon, testclear.com and 4uhealth.com.
I suggest using ChatGPT as I did and state your location.
For more details of go to the links above and check them out.
Here is the reply from my query to ChatGPT:
Here are real options in the USA if you want to test urine at home for opiates (which includes hydromorphone metabolites):
ScreenClear 9‑Panel Urine Drug Test Kit Cup
ScreenClear 6‑Panel Urine Drug Test Kit
$15.10 • Oz Drug Tests
$7.15 • Oz Drug Tests
🔎 Quick overview
ScreenClear 9‑Panel Urine Drug Test Kit Cup – Multi-panel test in a cup format you can use at home. Typical panel includes opiates (OPI) which will react if hydromorphone metabolites are present above the cutoff.
ScreenClear 6‑Panel Urine Drug Test Kit – Cheaper/basic option. Detects standard drug panels including opiates (codeine/morphine/hydrocodone/hydromorphone in many opiate panels).

testclear.com
SoberGuard 6 Urine Drug Test Dip Card – Dip card style (not a cup) with multiple panels, including opiates. Good if you want separate test lines per substance.
Notes on hydromorphone detection
Standard “opiates” immunoassay panels on over-the-counter kits do include hydromorphone metabolites in their cross-reactive group at typical cutoffs, so they’ll likely show positive if there’s enough in urine. �
testclear.com
These kits don’t measure concentration — only “present/absent” above a cutoff.
They’re for personal/peace-of-mind use, not legal, employment, or clinical diagnostics. For confirmed quantitative results, a lab test (like LC-MS/MS) would be needed. �

Where you can buy
You can order these kits online from major retailers (Amazon, Oz Drug Tests, drug testing supply stores) and have them shipped to the USA. Most ship either directly or through third-party sellers — just check the listing for delivery details.
If you need something that’s specifically designed to detect hydromorphone (not just the opiates panel), the only options are lab-based confirmatory tests (ordered through a clinic or lab service), not typical over-the-counter strips.
