A 28-year-old man and 55-year-old woman from Clacton were arrested on suspicion of the same offence at the address on Totlands Drive, the male was also arrested on suspicion of money laundering.
Drugs, cash and a stun gun were seized from the three addresses (Essex Police).
At the Dudley Road property, a 30-year-old woman and two males from the town, aged 26 and 27, were arrested on suspicion of possession of drugs with intent to supply and firearms offences.
Sgt Simon Tattersall, of the Tendring Community Police Team, said: "The warrants are part of our ongoing work to tackle serious violence, and drug dealing is often associated with violence and exploitation.
"We’ve managed to take a significant amount of suspected drugs off the streets and will continue to target individuals that we believe are involved in such crimes.
"Information from the community is really important in helping us do this, so if you know anyone who is involved, please tell us."
