Somebody is..

I like the way they try to protect children with a well meaning and  
only thinly disguided word of caution:

"Mephedrone powder is a very fine white coloured substance with a  
slightly sweet smell. To use it with plants simply add 1g to a  
standard watering can, ensuring that there is not contact with the  
stem. A full can of water with mephedrone product will cover between 2  
& 6 adult plants. We do not recommend the use of mephedrone powder  
with younger plants as this can have adverse effects."

so 1g is enough for 2-6 people? 6 seems to imply a level of frugality  
I have yet to see in any drug user, though..
