The US celebrity launched the range on Thursday as millions marked 4/20 – a so-called “high holiday” celebrating weed culture.
Her Kimoji goods include hats which boast “Never not high” and rolling papers emblazoned with her face.
She’s also cashing in with phone cases which say “Sorry I was high” and an eyepopping “ass tray”.
Addiction experts blasted her for goading her UK fans into getting high.
Head of drug use charity Resolve, Joe Heeney, said: “All this does is normalise drug taking. It will only encourage more young people to take cannabis.
“Kim Kardashian hasn’t thought about the impact of what she does on millions of teenagers.
“Anything people in the public eye say or do is instantly available to impressionable young people who think it’s cool,” he added.
The mum-of-two, 36, has 98 million followers on Instagram and 51 million on Twitter. The consultant psychiatrist and addiction specialist Dr Adam Winstock said Kardashian could use her influence to inform young people about safer drug use.
He said: “If she uses this new platform to educate and promote safer use with respect and responsibility towards her fans – good for her, I would be happy to help her.
“If she is just after a quick buck with no concern for the negative impact reckless promotion to young people then she could be doing harm.
“With a bit of advice she could be doing more good than harm.”
Fans lashed out, with one commenting: “Your morals and respect have left so much to be desired..”
Kim’s half-sister Kylie Jenner had been previously photographed wearing a cannabis leaf choker.
It comes after her rapper husband Kanye West launched a clothing range including a jumper with holes costing £1,745.
The music star claimed publicly that he was in £41million of debt.
