The Mexican middleweight still insists eating contaminated meat was the reason traces of Clenbuterol were found in the samples he gave in February.
But he was forced to scrap his May 5 rematch with Gennady Golovkin after the Nevada State Athletic Commission indicated he could face a one-year ban.
But Alvarez had the second half of a potential one-year ban suspended after co-operating with the NSAC and could now face Golovkin in a return of their controversial draw last year on September 15.
And Khan – who was knocked out by Alvarez in May 2016 – believes that sends out the wrong message.
He said: “The six-month suspension doesn’t mean anything because other fighters will see that and think ‘I can take anything to get jacked up and only have a six-month ban’.
“I hoped it would be more serious, a longer ban, to make sure that others fighters won’t follow. Life bans or at least a couple of years so that you feel it.
“Six months is not going to do anything, it’s barely one fight, he’ll be straight back into a massive fight again.
“It is only going to push young fighters toward taking stuff because of the short ban.
“When you get caught you will always be known as a cheat and you will never get that same respect. Once you are caught you are a cheat and will never respect any fighter.
“We don’t know if he has been doing it all his career, you can never respect the same person.
“I have been fighting for more than 10 years and I have never thought about taking anything. Why should we allow others to do it and keep that respect.
“I am a clean fighter, I can always have my head up high, but others out there will know they have cheated deep down. People will always remember Canelo as a cheat.”
Khan returns to the ring for the first time since his knockout by Alvarez, the fourth loss of his 35-fight career, against little-known Phil Lo Greco tomorrow night with his future on the line.
The 2004 Olympic silver medallist has had an illustrious career as he unified belts at light-welterweight before moving up in weight.
With that has come big pay days including the £9m he got in his last fight against Alvarez.
Lo Greco believes the pampered lifestyle that comes with being rich and famous will come back to bite Khan tomorrow night.
The Canadian said: “He’s been living a luxury, lavish lifestyle.
“There’s nothing wrong with that, but Marvin Hagler said it best - try getting up at 5am to go for a run when you’re wearing silk pyjamas. It ain’t going to happen.
“I know for sure he’s had a hard time getting up for this fight.”
