Darren McCash is also charged with money laundering.
All three men spent last night in police custody before they are due to appear at Southampton Magistrates Court today.
Four other suspects arrested as part of this investigation have been granted police bail until September 1 pending further enquiries.
They are two 50-year-old women from Southampton, 22-year-old woman from Portsmouth and a 17-year-old boy from Southampton.
