A senior bikie gang member was one of more than a dozen people arrested during drug raids spanning several weeks in northern Tasmania.
Illegal drugs with a street value of $350,000 were seized during the raids, which last week targeted several houses and a hotel in Launceston.
"We think this may put a sizeable dent in drug distribution around Launceston," Tasmania Police Commander Brett Smith told reporters.
"But we're not that naive to think that others won't pick up an seize an opportunity.
"We'll continue to target drug offenders. We have a list and we're going to work through the list."
Several hundred ecstasy pills, cocaine, methamphetamine, heroin and speed have been seized by police.
Four guns and three stun guns were also recovered as well as stolen property including cars, motorbikes, jewellery and a large number of power tools.
A 31-year-old man from Devonport, who investigators say is a senior member of the Outlaws motorcycle gang, was charged with trafficking in a controlled substance.
Another man, 38, from Newstead was remanded in custody after briefly appearing in Launceston Magistrates Court on Monday on drug and gun charges.
Several other people will be summonsed to appear in court.
Police said the raids and arrests happened over several weeks as part of a drug operation that began at the start of the year.
