I got fooled into thinking the crap sold on websites actually work 3 weeks ago.

I bought some Max Strength detox drink, followed the instructions to the letter and failed the UA.

Do NOT be taken in.

I got a retest on Tuesday but used the substitution method (got the urine from a non-smoking buddy) and had no problems.

So believe Burnt Toast...he knows what he's talking about.

My view is that substitution is the only safe method. Either do that or give up smoking.
