No such increase in drug use exists; It is purely a figment of your imagination (or an expression of your counter-factual expectations). Reality doesn't care what you think SHOULD happen.

There was a slight increase in cocaine use among the general population in 2007 (from 1% in 2004 to 1.6% in
2007) and again in 2010 to 2.1%. However cocaine use in the broader population remains relatively low. The rise in
2010 was mainly accounted for by 20 to 29 year olds.
Frequency of cocaine use in the general population remains sporadic, with the majority of Australians reporting
monthly or less frequent use in 2010.

Use of ecstasy in the general population has declined for the first time since 1995. The decline from 3.5% in 2007
to 3% in 2010 was statistically significant, and was driven by a significant decline in use among males over 14
(from 4.4% in 2007 to 3.6% in 2010), and young Australians aged 14 to 19 (particularly among females where use
declined from 6% in 2007 to 2.5% in 2010).
The decline in recent ecstasy use in Australia mirrors a downward trend in ecstasy markets recorded
internationally around 2010.
In 2010 the majority of Australians who used ecstasy reported using once every few months or less.

General population
•
Past year heroin use remains low among the broader Australian population at less than 1% in 2010.
Sentinel Groups
•
Among people who inject drugs there has been a decline in the prevalence of past 6 month heroin use over
time (from 79% 2000 to 58% in 2013), however daily heroin among heroin users in this group has increased to one
quarter (25%) in 2013.
•
Very small proportions of regular ecstasy users (4% in 2013) reported recent heroin use.

Prevalence of past year methamphetamine use remains stable in Australia at 2.1% in 2010.
•
Weekly methamphetamine use has remained stable between 2001 and 2010 (9.3% reported weekly or more use
in 2010, with the majority of Australians across all age groups reporting use every few months or less frequently.
•
Powder methamphetamine continues to be the form most used in the general population.
Sentinel groups
•
Among IDRS respondents, prevalence of past 6 month methamphetamine use overall remained stable between
2001 and 2011, however a decline was recorded between 2009 and 2010.
•
Among regular ecstasy users there was a decline in past 6 month methamphetamine use between 2003 (84%)
and 2009 (54%) and a decline in frequency of use. This decline is across all forms of methamphetamine but most
marked for crystal methamphetamine. Use has stabilised at a lower level in 2010 and 2011.
•
Shorter term trends show that crystal methamphetamine use in particular increased significantly between 2010
and 2011 among both IDRS and EDRS respondents

Suicide rates have not been increasing, despite media reports; according to a 2015 report by John Snowdon, in the Australian and New Zealand Journal of Psychiatry (

The Australian Institute of Criminology data show that
domestic violence declined between 2002 and 2012 (
source); The Victorian Royal Commission into Family Violence said it was not clear whether the prevalence of family violence was increasing, but it noted that greater reporting of family violence had led to an increase in incidents being recognised. (

So, in brief,
your claims are false..
Of the four things you cite as rising along with atheism, only the last - family breakdowns - actually might be rising; the others are stable or in decline. And family breakdowns - by which I presume you mean divorce or separation of married couples - are not actually a bad thing. When two people who don't want to live together are pressured to do so, that's a directly harmful situation; and the greater incidence of 'family breakdowns' of this kind are likely a major contributor to the decline in domestic violence.
You are not entitled to your own facts - No matter how much you might want these 'bad' things to correlate with increased atheism, they do not, in reality, do anything of the sort.
